These advantages make the TPMOS extra appropriate for being integrated with an SBD to reduce each conduction loss and switching loss. Therefore, the trench/planar 4H-SiC MOSFET built-in with SBD (TPSBD) is firstly proposed and studied. For the TPSBD, the static simulation outcomes present that the maximum reverse current without body diode turning on is 1320 A/cm2 within the third quadrant. In the double pulse check with a load current of 1000 A/cm2, the physique diode of the TPSBD is successfully suppressed.

However, the physique diodes of the other three MOSFETs turn on and contribute the 75{4ab6b815505e0e8839b52a7724d5aa8dc74c8c2c76e45856ab848d678c7b6ed9} of the freewheeling currents, even though an exterior SBD is anti-parallel with these MOSFETs. The body diodes still contribute 25{4ab6b815505e0e8839b52a7724d5aa8dc74c8c2c76e45856ab848d678c7b6ed9} of the freewheeling currents, despite the fact that the active area of the anti-parallel SBD increases three times. Compared with TMOS, DTMOS and TPMOS, the reverse restoration charge of the TPSBD reduces by 91{4ab6b815505e0e8839b52a7724d5aa8dc74c8c2c76e45856ab848d678c7b6ed9}, 88{4ab6b815505e0e8839b52a7724d5aa8dc74c8c2c76e45856ab848d678c7b6ed9} and 96{4ab6b815505e0e8839b52a7724d5aa8dc74c8c2c76e45856ab848d678c7b6ed9}, respectively.
