Default Re: Help needed identify Diode - PSU FSP Hexa 500W
Did you remove it and test it off the board? It is connected in parallel with the resistor R84 (I cannot cleary see the print on the body, but more likely to be a 10 Ohms resistor).
BTW, that diode/resistor network is for Gate discharge which is connected to Gate of the MOSFET, you should check and see if the MOSFET is OK or not.
Since the main fuse is blown, you need to check all the power semiconductor devices for shorts.
