Oct 18, 2019 While the body diode is in reverse recovery, its drain-source voltage rises. This behavior can cause a false turn-on of the internal parasitic NPN bipolar transistor, destroying the MOSFET. There is really only one disadvantage of having no body diode: higher reverse voltage drop. It should be mentioned here, that in SiC MOSFETs, a separate antiparallel diode is needed, as the intrinsic body diode of the SiC MOSFETs are unreliable. But in Si, Eamon is correct, the body.
- Discover our range of discrete IGBTs without Anti-Parallel Diode: low switching losses, low conduction losses, increased efficiency. Perfect for hard switching applications like solar, inverterized drives, uninterruptible power supply (UPS) and welding systems.
- Intrinsic MOSFET body-drain diode and Schottky features AN4789 4/16 DocID028669 Rev 1 2 Intrinsic MOSFET body-drain diode and Schottky features In Figure 1, the typical symbol for an N-channel power MOSFET is shown. The intrinsic body-drain diode is formed by the p-body and n-drift regions, and is shown in parallel to the MOSFET channel.
