Product details

35 ns trr — where this diode earns its keep

Its 35 ns reverse recovery time places it in the ultrafast class — the recovery charge is low enough to keep turn-off losses under control in continuous-conduction-mode PFC boost stages and hard-switching output rectifiers up to the 100 kHz range.

D2PAK common-cathode pair — footprint and thermal

Forward voltage and leakage at temperature

Maximum forward voltage is 1.9 V at 15 A per diode — a 28.5 W conduction loss per die at full rated current, so the dual-package dissipates up to 57 W total. The 20 µA reverse leakage at 300 V is a room-temperature figure; leakage doubles every 10°C above 25°C, so at 125°C junction the standing loss from leakage alone approaches 0.5 W.
