yep it's very strange one moment it's cool next moment it explodes. i am afraid to put a bigger diode cuz if the same happens with it may catch fire... i think i found the write diagram, i will post it tomorrow.
regards.
Yep that true. May be my diode was not good. Can a diode just die and behave like a closed circuit. After studying the diagram i feel more confident.
What happens if my Drain and Source is connected the other way round?? cuz i connected the Drain and Source blindly where the NAVY BLUE Point marking are in the diagram.
Yes. But there's always a reason for it dying. Wrong polarity, excessive current or excessive voltage will kill it.
You stand a good chance of destroying the FET.
You should always download the datasheet for any electronic device and check the pinout before connecting it up.
