Due to the way that FETs are built, each FET has a diode built-in, known as a “body diode”. You can’t avoid this diode – it’s there to stay; you can only account for its existence when ...

The schematic above shows the P-FET on the high side of the circuit ... This design also uses a clamping diode to keep the gate voltage within a safe range. But there are P-FETs out there that ...
