Do you know where the "Schottky" in the SS14 Schottky barrier diode comes from?

It actually originates from a physicist named Walter H. Schottky, who invented it. Unlike conventional diodes using a P-N junction, the SS14 Schottky barrier diode is uniquely crafted based on the direct contact between a metal and a semiconductor.

The SS14 diode is crucial for rectification and circuit protection. It allows current to flow in only one direction, effectively preventing short circuits and protecting the system. Thanks to its compact structure and small footprint, the SS14 fits perfectly into various modern devices, making it a go-to choice for global buyers.

Now, here comes the most critical question: Do you know how to judge if an SS14 diode is good or bad?

First, identify the polarity - the end marked with a white line is the cathode (negative). Set your multimeter to the diode test position and connect the probes:

The Good Sign: In the forward direction (red probe to positive, black to negative), a good diode will show a regular voltage reading. When reversed, it must block current and display "1" or "OL".
The Bad Sign: If it displays "1" or "OL" in both directions, or shows a reading/beeping when reversed, the diode is damaged.
