80 V, 5 A dual Schottky in a TO-220 full-pack
Its 745 mV forward voltage at 5 A and 175°C maximum junction temperature suit it for high-efficiency power conversion in switch-mode power supplies, freewheeling diodes, and polarity protection circuits where the TO-220 full-pack package provides electrical isolation from the heatsink.
Buyers should qualify the part for their BOM line and plan for a last-time-buy or a validated replacement.
The 80 V reverse voltage (Vr max) gives headroom for 48 V and 60 V bus rails, common in telecom and industrial power supplies. The 5 A per diode average current, combined with the 175°C junction rating, allows the part to handle sustained loads in a compact through-hole package without derating at typical ambient temperatures. The 745 mV forward drop at 5 A is a Schottky-level figure that keeps conduction losses lower than a comparable ultrafast silicon diode, which matters when the rectifier is in the output stage of a 100 W-class converter.
