Mosfet reverse recovery time
WebMOSFET, it is recommended not to add an antiparallel diode with the GaN FET to conduct the reverse current. Adding an antiparallel diode adds output capacitance to the switch node and increases switching losses. Instead, the third quadrant losses can be minimized by optimizing the dead time. 2 Mechanism of Reverse Conduction in GaN FETs WebMay 6, 2024 · The company claims that the reverse recovery time of the new Super Junction MOSFETs is just 105ns, which makes it possible to reduce switching loss by …
