WEET Shares What does Forward Voltage Drop mean and What is the meaning of Reverse Voltage

    WEE Technology Company Limited
    Manufacturer of Surface Mount (SMD) and Through Hole (DIP) Diodes & Rectifiers

    What does Forward Voltage Drop mean?
    Electricity uses up a little energy pushing its way through the diode, rather like a person pushing through a door with a spring. This means that there is a small forward voltage drop across a conducting diode. It is about 0.7V for most diodes which are made from silicon.The forward voltage drop of a diode is almost constant whatever the current passing through the diode so they have a very steep characteristic (current-voltage graph).

    What is the meaning of Reverse Voltage?

    When a reverse voltage is applied a perfect diode does not conduct but real diodes leak a very tiny current (typically a few µA). This can be ignored in most circuits because it will be very much smaller than the current flowing in the forward direction. However, all diodes have a maximum reverse voltage (usually 50V or more) and if this is exceeded the diode will fail and pass a large current in the reverse direction, this is called breakdown.

    We suggest you to read more technical information about diodes symbols. Below article will tell you what the diodes symbols stand for.

    If you still have some doubts, please contact with WEET sales engineers. We are ready to help you.

WEET Transistor TO-220 Style Power Package P Channel MOSFET PMOS For Switch Circuit Application

    WEE Technology Company Limited
    Manufacturer of Surface Mount (SMD) and Through Hole (DIP) Diodes & Rectifiers


    Comparison between P-channel and N-channel MOSFETs in an application


    The source voltage of an N-channel MOSFET when used as a high side switch will be at a higher potential with respect to ground. Thus, to drive an N-channel MOSFET an isolated gate driver or a pulse transformer must be used. The driver requires an additional power supply whilst the transformer can sometimes produce incorrect conditions. However, this is not the case with P-channel. It is easy to drive a P-channel high side switch with a very simple level shifter circuit. Doing this simplifies the circuit and often reduces the overall cost. 


    However, the point to be noted here is that it is not possible to achieve the same RDS(on) performance for a P-channel MOSFET as for an N-channel with the same chip size. As the mobility of the carriers in an N-channel is approximately 2 to 3 times higher than that of a P-channel, for the same RDS(on) value, the P-channel chip must be 2 to 3 times the size of the N-channel. Because of the larger chip size, the P-channel device will have a lower thermal resistance and a higher current rating but its dynamic performance will be affected proportionally by the chip size. So, in a low frequency application where the conduction losses are prominent, a P-channel MOSFET should have a comparable RDS(on) to that of an N-channel. In this case, the P-channel MOSFET chip area will be larger than that of the N-channel.


    Also, in high frequency applications where the switching losses are dominant, a P-channel MOSFET should have similar total gate charges to that of an N-channel. In this case, a P-channel MOSFET has a similar chip size but a lower current rating than that of an N-channel.

    TO-220 package is a kind of in-line package commonly used in high-power transistors and small and medium-sized integrated circuits.
    Among them, to is the abbreviation of transformer outline.

    Generally, TO-220 is a single row straight plug, which can lead out 3, 5 or 7 feet. Standard TO-220 footprint (seven pins).
    TO-220 and to-202F are basically the same shape, they are all 3-pin single in-line package with 2.54mm pin pitch.
    To-220F is a full plastic package, and there is no need to add insulation pad to the radiator.
    TO-220 with metal sheet connected to the middle foot, if the radiator is installed, an insulating pad shall be added.

    Performance comparison and difference between TO-220 and TO-220F
    TO-220, TO-220F: TO-220F is a full plastic package. When it is installed on the radiator, there is no need to add an insulating pad;
    TO-220 with metal sheet is connected to the middle foot, and an insulating pad is added when the radiator is installed.
    The MOS tubes of these two packaging styles have similar appearance and can be used interchangeably.
    The difference of PD between TO-220 and TO-220F is due to the difference of RJC between the two packages.
    TJ is generally considered to be 150 ℃. TJ = TC + PD * RJC, in which TC is the temperature of the structure shell closest to the wafer,
    PD is the power consumption carried on MOSFET, and RJC is the thermal resistance of judgment to case.

WEET Strong KBL610 KBU810 KBP310 Round 4 Radial Leads Single Phase Bridge Rectifiers

    WEE Technology Company Limited 

    Manufacturer of Surface Mount (SMD) and Through Hole (DIP) Diodes & Rectifiers


    Single-phase rectifier bridge: four pins, including two power inputs (L, N), two DC outputs (+,-)

    How to connect a flat bridge rectifier bridge and how to measure the quality of the rectifier bridge? From the pin display in the figure below, we can clearly see that one of the four pins of the flat bridge KBU810 has a longer one. In the flat bridge rectification bridge line, we need to use this "special" pin as a reference, find out the positive and negative poles of the rectifier bridge and then connect them correctly.


    Like the KBU810, other flat bridge rectifier models also have the characteristic of unequal length of four pins, which is the most critical part to distinguish the positive and negative poles of the flat bridge stack. The longest pin represents the positive pole of the product, and there will also be a positive symbol on the product.


    Round feet and flat feet are just different package specifications. Others are not different. Due to the different design of the PCB board, the structure of the leads that need to be used will be different.

    GBPC3510-New package aluminum bottom plastic Shell - More stable and reliable

    GBPC3510 uses a new aluminum bottom plastic case package. This new package is very different from the metal zinc case used by KBPC3510, which has better heat dissipation and stability. Customers who have used metal zinc shell packages will feel this way. The heat dissipation is relatively not prominent. The large amount of thermal energy accumulated in the long-term operation of the internal chip cannot be effectively exported, which directly affects the reliability of the bridge stack. The GBPC3510 is packaged in a new aluminum bottom plastic case. Aluminum has a high conduction efficiency and can conduct heat quickly, which greatly improves the reliability of the power supply.


    GBPC5010 adopts aluminum bottom plastic Shell - Better protect chip and more secure

    We know that GBPC3510 is a semiconductor power device, and the chip will heat up when it is working. Because the chip is wrapped with epoxy resin, the resin will expand slightly when the chip heats up, and when the rectifier bridge stops working, the resin will shrink slightly. Because the thermal equilibrium point of metal zinc and epoxy resin is not consistent, if the resin and the shell are not synchronized when the heat rises and contracts, it will cause a hard strain on the chip. Although this hard change is not great for the entire rectifier bridge, it is enough for the built-in chip to damage the chip. The GBPC3510 special design will be able to prevent the risk of wonderful chip is hard force injury, it can be more good to protect the chip from being damaged.


    GBPC3510 with aluminum bottom plastic Shell - Thinner Volume

    GBPC3510 uses the GPP passivation process for gold-plating large chips. The GPP passivation process is also called the glass passivation process. It is a layer of glass protection on the surface of the chip, which can better prevent chip oxidation and improve chip stability. The highlight is that it can reduce the thickness of the chip, which is in sharp contrast to the thick white glue wrapped with traditional pickled chips. Therefore, using a thinner GPP chip can make the GBPC3510 have a thinner volume.


    Advantages and disadvantages of square rectifier bridge zinc shell and aluminum bottom plastic shell:

    The galvanized shell rectifier bridge has a metal zinc envelope inside and a potted black plastic seal inside. The square bridge with this packaging method has lower cost and can be well applied in some places where the temperature rise is not high. However, the heat dissipation performance of this kind of bridge stack is not as good as the bridge stack of aluminum bottom plastic shell. On the contrary, the bridge stack of aluminum bottom plastic shell has a cooling aluminum plate under the square bridge stack, which can greatly improve the heat dissipation performance of the bridge stack. But relatively speaking, its cost will be higher, and the cost issue will be considered in our actual application.

WEET Best Offer of SMAJ15CA SMAJ12A SMAJ6.0CA 400W Transient Voltage Suppressor TVS

    WEE Technology Company Limited 

    Manufacturer of Surface Mount (SMD) and Through Hole (DIP) Diodes & Rectifiers

       

    Important parameters of TVs

    A major challenge in automotive design is to protect automotive electronic equipment (such as control units, sensors and entertainment systems) from damaging surges, voltage transients, ESD and power line noise. The use of transient voltage suppressor (TVS) is an ideal solution to protect automotive electronic equipment. Next, we will discuss the key parameters of TVs devices - power level, off state voltage and maximum breakdown voltage.


    Power level

    The power level of TVs is the surge absorption capacity under specific test or application conditions. Vishay's TVs products use industry standard 10 / 1000 μ s pulse waveform

    (Bellcore 1089 standard) as the test condition, as shown in Figure 1. This test condition is different from the 8 / 20 μ s pulse waveform of TVs ESD test


    Breakdown voltage (VBR)

    The breakdown voltage is the voltage at which the device enters the avalanche breakdown, which is tested according to the current specified in the data sheet.


    Maximum breakdown voltage (VC: clamping voltage)

    Clamping voltage level that appears on TVs at the specified peak pulse current level. The breakdown voltage of TVs is measured at very low current, such as 1 mA or 10 Ma, which is different from the actual avalanche voltage in application conditions. Therefore, semiconductor manufacturers will indicate typical or maximum breakdown voltage under high current conditions.


    Off state voltage (VWM: working off state reverse voltage)

    Off state voltage refers to the maximum voltage when TVs is not broken down. It is an important parameter of protection device which does not work under normal conditions. In automotive applications, the regulation of some automotive electronic products is realized by "step protection". This test condition is to supply 24 VDC to 12 V electronic equipment and 36 VDC to 24 V electronic equipment within 10 minutes without causing damage or circuit failure. Therefore, for automotive electronic products, off state voltage is a key parameter of TVs devices.
