first of all im not at all an experienced electronics engineer..
hi all... i had a nice firework just before posting this thread :-D...
By googling i found that cep83a3 is an N-Channel Enhancement Mode Field Effect Transistor.
Again by Googling i found that cep50no6 is also N-Channel Enhancement Mode Field Effect Transistor.
so i replaced 83a3 with 50no6.
these components were from my two old UPS'. i was trying to make it working. because i saw 83a3 burned. so i replaced.after replacement when i switched on(no AC connected). the UPS powered up and suddenly switched-off.hence i thought that it might be because of low battery. then i connected AC power... :razz: ... fireworks fireworks... the one i changed cracked again and another one nearby also cracked.. with burned board print..
isnt this a substitute for the one i had mentioned? if not how can i find one:thinker:.
