    What is a "Bidirectional Diode"? and what is it used for?

    Call me an Olde Geezer, but I seem to remember that a diode is supposed to be uni-directional.

    Please respond quickly, as I do not have too much hair left to pull! :D

    In its pure form you need to look at something called a DIAC, and in its triggered form look at something called a TRIAC.

    Oh, and put a hat on and pull the hat instead!

    Thanks, people! DIACs and TRIACs I know of; calling them "bidirectional diodes" sounds like something marketing would come up with.

    And thanks, Dave for the advice on the hat! ;)

    Sounds like a functional description from someone who doesn't know the name of the actual device. Basically you are right - marketing speile.

    No probs, had to do it myself - now I just shave my head!
