I couldn't find a definitive answer.
What's more suitable to drive a 5v relay from a 3.3v MCU, a MOSFET or a BJT Transistor? NPN or PNP?
I will be using a Schottky SS34 as flyback diode. Relay consumes 75mA. I can use NPN transistor MMBT3904LT1G or N-Channel MOSFET BSS138 for turning on the relay, emmiter/source to ground, would that be ok?
