They are also known as PN diodes, PN junctions, and small-signal diodes. Zener Diodes Zener diodes act as normal rectifiers until the applied voltage reaches a certain point. At this point (the Zener ...

If you wonder why you care about high speed in a diode, [GreatScott] has a good demo of rectifying a signal with a regular diode and a Schottky. At a certain frequency, the normal diode starts ...

A single rectifier diode will only allow half of an AC signal to propagate while blocking the reverse polarity so long as it does not exceed the breakdown voltage. Several circuits are available that ...
