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 have different packing methods for different package Bridge Rectifiers. For small SMD products, we have ammo packing.

For small dipped products, we adopt tube packing. But for large packages, we choose bulk and box packing. Please refer to some of WEET strong Bridge Rectifiers in box packing.

Below table is WEET standard packing information, if you need special packing, please talk to your WEET sales engineers. Thank you for understanding.

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.

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.
