Hi,
I made a really simple PWM generator but the mosfet placed in the circuit keep getting damaged even though they are not heating up.
The load in the schematic is a 20ohm heating element but i also tried to replace it with much led and resistor but the mosfet still get damaged after 1 or 2 runs.
The mosfet is cj3400. Any suggestions are appreciated.
Thank you.
There's also a 10k pull down resistor between gate and source with is not present in the schematic
