Okay, I'm building a serial link cable for my TI calculator and the plans call for two zener diodes. What exactly is a zener diode? Is that just a regular diode, because I have some diodes, and if ...

A curve tracer, at its simplest, displays a V-I graph of the DUT, most easily demonstrated by a diode plot. A zener diode curve (Source: Tom Gootee) One doesn't need a very fancy circuit to trace out ...

Zener diodes can be downright baffling for beginners, especially when mistakenly thrown in a circuit in place of a regular 1N4001. [Afrotechmods] put together a great video explaining their ...
