1 Answer. Yes, power MOSFETs have a parasitic diode called body diode. Thanks to this diode, only a MOSFET can function as a one-way switch. Only a MOSFET can disconnect the opposite direction, because the diode works independently of the door.

The MOSFET Transistor (Metal Oxide Semiconductor Field Effect Transistor) is a semi-conductor device widely used to switch and amplify electronic signals in electronic devices.

1 Answer. Although the body diode in MOSFET is often conceived as a physical diode next to MOSFET, it is not really a discrete building block of a MOSFET. It is a parasite that exists intrinsically because of the accumulation of silicon in a MOSFET. There is no MOSFET without body diode, it is a fact of life.

MOSFET is a two-way device, from the point of view that terminals called source and escape can be changed. One of the other two can be chosen as source, and the voltage of the portal in relation to this terminal is greater than the voltage of the device threshold.

MOSFET is a symmetrical device, so the answer is yes. However, if when designing your circuit you have connected or body to one of the terminals, I would like this terminal to be provided.
