Do all MOSFETs have body diodes?

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.
