80 V, 5 A Schottky pair in D²PAK
The STPS10M80CG-TR is a dual Schottky rectifier from STMicroelectronics, with two 5 A diodes in a common cathode configuration. The pair shares a D²PAK (TO-263AB) surface-mount package, making it a straightforward fit for OR-ing diodes, output rectification in switch-mode supplies, and polarity protection in 48 V or 24 V telecom and industrial rails.
STMicroelectronics lists the STPS10M80CG-TR as Obsolete. That means no further factory orders, no last-time-buy window — the only channel is the open market.
The 80 V reverse voltage gives you headroom on a 48 V nominal bus — think 60 V transient tolerance with margin. The 5 A per diode is the average rectified current; in a typical forward converter or OR-ing application you derate for ambient temperature and the shared tab dissipation. The 20 µA reverse leakage at 80 V is a room-temperature figure; junction temp at 175 °C max means leakage climbs, so keep the thermal path to the tab clean. The 705 mV forward drop at 5 A is typical for a Schottky at this voltage class — expect it to rise with junction temperature, which is normal.
