SiC Schottky — zero-recovery-loss switching for the PFC stage
It belongs to the Automotive, AEC-Q101 series, qualified for deployment in automotive power conversion stages. The SiC Schottky structure delivers zero reverse-recovery charge, which means the switching losses in a hard-switched PFC or DC-DC converter are dominated by the output capacitance, not the diode recovery.
Forward drop and thermal budget at 10 A
At that current the conduction loss is 17.5 W per diode, and with two diodes in the TO-220 sharing the common cathode tab, the total dissipation drives the heatsink selection. Reverse leakage is 100 µA at 650 V, which is negligible for conduction losses but worth noting for standby power budgets in always-on automotive modules.
For dual-sourcing resilience, a buyer would need to qualify a functionally equivalent SiC Schottky from another supplier against the same 650 V, 10 A, TO-220 common-cathode footprint — a cross-reference that requires bench validation of the switching behaviour and thermal impedance.
Package and mounting — the TO-220 tab
The TO-220-3 through-hole package has the common-cathode tab as the main thermal path. The mounting torque on the screw to the heatsink matters — overtightening cracks the epoxy body, undertightening leaves an air gap that raises the junction temperature.
