Alternative for IRF520 mosfet in Arduino shutdown schema I’am using IRF520 mosfet according to this schema to shut down Arduino by low level on output to 10K ohms resistor

Schema of my device is



The issue is that IRF520 took too much place

Is it possible to substitute IRF520 with smaller mosfet?

Additional info:

I measured average power consumption – it’s about 22 mA on 12V = 0.264W

IRF520 is for 70W max according to datasheets.

The base schema is
For what you are trying to do, any transistor, bjt or MOSFET, would work. 2n2222 or 7000 for example. Irf5x0 is actually a poor choice here. It only worked due to the low load being switched.
