Reverse Polarity Protection

This circuit uses a mosfet to prevent current flow if power is connected backwards. The zener diode limits the gate voltage to protect the mosfet.

Why don't you use a normal diode for reverse polarity protection?

P-channel mosfet, not weird :)

I have made a circuit like that, but a little more efficient

hmmm... But how to deal with reverse current using this method?
