Product details

80 V reverse voltage, 7.5 A per diode — the ratings that matter

This is a dual Schottky rectifier in a common-cathode configuration, meaning the two anodes are separate and the cathodes share a common pin — typical for center-tapped secondary rectification or OR-ing diodes in redundant power supplies. The forward voltage is 725 mV at 7.5 A, which is a Schottky-typical drop that keeps conduction losses manageable in a 15 A total-output design. Reverse leakage is 25 µA at 80 V — a standard figure for a 80 V Schottky at that voltage stress.

D2PAK package — footprint and thermal reality

The part comes in a TO-263-3 (D2PAK) surface-mount package with two leads plus the tab. Without adequate copper area, the junction temperature will limit the usable current well below 7.5 A per diode.

Frequently asked questions

What is the replacement for STPS15M80CG-TR?

No official successor is listed by STMicroelectronics. A functionally similar common-cathode Schottky in D2PAK with 80 V and 7.5 A per diode would be the closest cross, but pin compatibility and thermal performance must be verified against the original layout.

What package does STPS15M80CG-TR come in?

The tab is the common cathode.
