- The body diode of the MOSFET forms between the n-layer of the MOSFET’s drain and the p + well of the device’s source. This is the diode depicted in virtually all MOSFET datasheets.
- Generally, low power MOSFETs have not any Body Diode or Intrinsic Diode but the high power rated power MOSFETs have. The body diode is also called parasitic diode or internal diode. We need to connect an external diode in antiparallel with the low power MOSFETs for certain applications.
The MOSFET specifications will state a maximum energy the MOSFET can take in avalanche mode. Energy is 1 / 2 LI 2 where L is the inductance and I is the current. Fortunately, in most circuits, the energy the MOSFET may have to clamp is that contained in the rather small (lumped) inductance of the battery and its leads.
