600 V, 80 A — the switching-loss ceiling
Its 115 ns reverse recovery time (trr) sets the turn-off loss in hard-switched PFC boost, inverter freewheeling, and output rectifier stages — the lower the trr, the less energy dissipated per cycle at high frequency.
115 ns trr — what it buys the BOM
A 115 ns trr at 80 A and 600 V means the diode recovers fast enough for switching frequencies up to roughly 50 kHz in continuous-current-mode boost converters without excessive ringing or snubber losses. The forward voltage is 2 V at 50 A — a 100 W conduction loss at full rated current that the TO-247-3 case must sink through the junction-to-case thermal path. Junction temperature range extends to 175 °C, which allows the 80 A average rating to hold in a 100 °C ambient with a properly sized heatsink. Reverse leakage at 600 V is 40 µA — negligible at room temperature but will double with every 10 °C rise, so the thermal design should budget for leakage-induced self-heating at high line.
