    Hi,

    "9831" most probably is the date. YYWW

    Just a guess: TG179 maybe is a BC179 in plastic case.

    You could tell more about the PCB and the circuit.

    Thanks for the response mr KlausST...I dont have schematic, and so I sketched it myself...how do you find it? The pin configuration also like hard to guess...

    Re: IFC TG179 TO-92 (transistor)

    The first resistor connected to +15Vdc is 100K and the next resistor is 200 ohms. The part number of zener diode is 1N4577. Any expert please help identify this IFC TG 179 is a mosfet or transistor...really appreciate any support...thanks

    Re: IFC TG179 TO-92 (transistor)

    Hello All...this TG179 for me is mosfet and not transistor....Because of zener diode connected on the middle pin which i believe a gate pin. Any opinion from you guys? thanks

    Ok i replaced the TG179 with mosfet TN0604N3...Will update you once we test at machine. Probably by next week...Wish me luck
