Step back and breathe. A 10K from gate to ground will do just fine. Southpark Edison Member Posts: Runaway, that would be true if it were the same mosfet. It worked for the first time but afterward, the drain pin got overheated and the soldering got melted and I had to solder it back but afterward, it got melted 2 more times due to overheating.

Hi, Please post some pictures of your project so we can see you component layout, particularly the solder joints at the MOSFET and show us how you have it connected to the powersupply. You need a "logic level" transistor for that application. Vgs is at 10V to fully turn on the transistor. Until then the pin is a floating input.

I'm thinking the gate was not at 0V, but somewhere around the Vgs th causing the mosfet to dump a bunch of voltage as heat. Please note down, power supply connections and pin names.
Let it ALL hang out!! Posting the sketch and a good photo of the actual situation relate more than a "fritzy thing" can.

Can you please post a copy of your circuit in a picture of a hand drawn circuit in jpg, png? That is why it gets hot.
Most of the issues ratasheet probably be solved if arduino project guides involving mosfets have some kind of big bold dataaheet thing with big fonts at the beginning of the guide The MOSFET is heating only when it doesn't conduct electricity, it seems that the overheating problem had encountered since I've tried to run the motor on a PWM signal although I'm not really sure if it's related or not.

You also need a pulldown resistor on the gate. It simply isn't a LL mosfet nor is it marketed as such. It worked for the first time but afterward, the drain pin got overheated and the soldering got melted and I had to solder it back but afterward, it got melted 2 more times due to overheating.
That probably applies to maybe any transistor Runaway, that would be true if it were the same mosfet. A 10K p55nf6 gate to ground will do just fine. Still, dataxheet what I gathered, the heating problem came with the mosfet supposedly being OFF. Can somebody help me to solve the overheating issue?

Tom It's not a hobby if you're not having fun doing it. Here is the data sheet for that transistor. Much more informative than an Ebay ad.

Without it, the gate can be left floating somewhere between off and on.
