Hello. I am working on a xbox one powersupply (no data or schematics). I accidentally shattered a zener diode to pieces when removing a TNY276. There is no numbers on the pieces. I have looked at the data sheet for the TNY and the is no use of a zener on that pin.
I am guessing it is being used as voltage protection. It goes from the source pins on TNY (ground) to EN/UV pin which goes directly to the collector of the optocoupler.
The datasheet says absolute maximum voltage for this pin is 0.3V to 9V. And underneath that it says EN/UV Pin Voltage is:
min: 1.8v, typ: 2.2v, max: 1.6v.
What voltage should I be counting on it using? The 2.2v typical I guess?
So should I use a 2.2v zener? If I would to use a 2v zener would it affect the output of the TNY since this pin is used to control it? The second question is just for learning more.
Thanks for any help!
