The 660 mV forward voltage at 15 A and fast recovery (≤500 ns, >200 mA) make it a fit for high-frequency switching power supplies, output OR-ing, and freewheeling diodes in DC-DC converters — not a 50/60 Hz line rectifier.
New designs should not target this order code. There is no official ST successor listed for this exact part number.
The 60 V reverse voltage (Vr) sets the maximum DC blocking voltage — adequate for 48 V rails with margin, but tight for 48 V telecom with transients. The 60 µA reverse leakage at 60 V is typical for a 60 V Schottky at 25°C; expect it to rise significantly at 125°C junction, which matters for standby loss in high-temperature designs. The 15 A per-diode average current (Io) is the thermal rating — derating for ambient temperature and heatsink is required; the D2PAK (TO-263AB) surface-mount package conducts heat through the tab, so PCB copper area is the heatsink.
The D2PAK (TO-263AB) is a surface-mount package with two leads plus a large tab that carries the common cathode connection. The tab is electrically live — the PCB copper pour must be isolated from other nets. This package is common across many dual Schottky parts, so a pin-compatible replacement search should start with the same footprint.
