Over Voltage and Reverse Voltage Protection Circuit
Reverse Polarity Protection Circuit using Diode OR P-Channel MOSFET
Simple reverse-polarity-protection circuit has no voltage drop - EDN
Rick on Twitter: "Quick #electronics tip: You can use a p-channel mosfet and a resistor to add reverse polarity protection to a circuit if a diode doesn't work due to it's voltage
