hey people, how critical is it to replace glass zener diodes as far as exact numbers? or can they be matched by use of multi meter ohms or otherwise. these zeners are in a mosfet driver section i guess for voltage spikes.
You can't measure the voltage rating of a zener diode with an ohm-meter. Just look at its datasheet. Many Mosfets have "a zener diode" built-in from drain to source. It has a very high avalanche current rating.
Ok I've got a question... I've seen on some high current inverter circuits and on some DC PS circuits the transistors' emitter and collectors are put in parallel and the bases are connected to each other. Or in PS transistors are put in parallel again to make the supply able to carry 20 or 30 amps. Does this kind of connection similar to putting batteries in parallel to increase their current capacity?
