    Closed: Re: Is it a transistor or a mosfet?

    Thanks for the inputs...but the low-ohm pins are the middle pin and the 3rd pin...Which based from JFET TO-92 pin configuration the pins are Source and Gate...So it should not read low-ohm, right?...

    I tried removed and discharged all pins by shorting it...But the low-ohm still remain about 10 ohms. And i believe it can't be middle pin and 3rd pin got low ohm in TO-92 right?

    Closed: Re: Is it a transistor or a mosfet?

    The original part actual is shown in the image below. I found it shorted (pin2 & pin3). The problem is I couldn't find that component online. Even datasheet is hard to find. Thus I am now having...

    It acts like electronic switch that turns on/off the bulb. It's either mosfet or transistor. Need more opinions from experts...thanks in advance.

    OK so for this case, I will use resistors. I got here 20-ohm/25W (18qty) + 10-ohm/20W (2qty). Total 380-ohms. I want to test with 1A load set-up...Thanks to all.

    Closed: 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
