Its 85 ns reverse recovery time (trr) keeps switching losses low in continuous-conduction-mode PFC stages, flyback snubbers, and boost converters where a standard recovery diode would overheat. ## 1 kV blocking, 8 A forward — derating for the real load The 1000 V DC reverse rating gives headroom on a 400 V bus (typical PFC output) for line transients and ringing. ## TO-220-2 with insulated tab — mounting and thermal path The through-hole leads are suited for PCB mounting or point-to-point wiring in power supplies and motor drives.
