Hey Guys I am doing some work on a Computer Power Supply and I need to identify the control transistor for the relay circuit.
Can anyone please help me out ?

According to the smd code book (google
) it is probably a FMMT-A42R high voltage transistor.
No way, it's nfet or pnp/npn just verify relay wiring. If it's just relay bobbin any nfet or bipolar with Vcc/Ic respect will do

I got SMD marking code 7E as PNP
MMBTA92I got SMD marking code 3E as NPN
FMMTA42OP should check if the emitter goes to GND, I expect that and an NPN.
What is the coil voltage of the relay?
