Help with diode dissipation - Arduino UPS
Peabody:
I tested the IRLML6401 mosfet I had chosen, and at 1A I'm getting a 0.1V drop across the mosfet. That indicates Rds of about 100mΩ. That's double what the datasheet says it should be, but I was using a breadboard, so that may have been the source of the additional resistance. Anyway, if my math is right, that's 100mW dissipated in the SOT-23 mosfet, which I think it should handle ok.
