Splet12. avg. 2008 · I checked the short with a continuity checker. and it is shorted from drain to source. I'm no where near the rated power factor, even if the motor ran full 3A current at Vds of 17v. still the power diss. would be 51W. But the Mosfet is not operating at that extreme. They just want to burn out running at Vds 3v. Splet06. maj 2024 · I'm trying to use an Arduino Uno to control a 12V signal using an N-channel MOSFET. After doing some research, I decided on the TN0702 and ordered a couple in case of problems. I supplied my MOSFET with 5V at the gate, connected the drain to my 12V high and the source to ground. I also added a resistor behind the gate. My first couple of tests, …
