The STPS20M60CT is a dual common-cathode Schottky rectifier from STMicroelectronics, rated for a maximum reverse voltage of 60 V and an average rectified current of 10 A per diode. The 570 mV forward voltage drop at 10 A is typical for a 60 V Schottky in this current class, keeping conduction losses manageable in a 20 A total-output design.
Housed in a TO-220-3 through-hole package with the supplier device code TO-220, the STPS20M60CT mounts into a standard 0.1-inch pitch footprint. The metal tab is the common-cathode connection and should be soldered to a heatsink pad or clamped to a thermal interface for junction temperatures up to 150°C. The 65 µA reverse leakage at 60 V is a room-temperature figure; expect leakage to rise with junction temperature, so derate the reverse voltage margin in high-ambient environments.
