Forward voltage sits at 780 mV at 10 A, which keeps conduction losses manageable in switching power supplies, OR-ing diodes, and output rectification stages. ST lists this part as Obsolete. That means no further factory orders are being accepted, and the last-time-buy window has closed. If you have a board in production that calls out the STPS20SM80CFP, you are now looking at the surplus and independent-distribution channel to keep the line running. ## Replacement path ST does not list a direct drop-in successor for the STPS20SM80CFP in the TO-220AB Full-Pak. A functionally similar Schottky in the same package with 80 V / 20 A capability would need to match the common-cathode pinout and the isolated-tab footprint. Without an official cross-reference, the safest move is to compare the forward voltage curve, reverse leakage at temperature, and thermal resistance against a candidate like the STPS20SM80CG (non-isolated TO-220) if board clearance allows an insulating kit. For a pin-compatible replacement in the Full-Pak, we can search the surplus channel against your target price and volume. ## Key ratings at a glance Reverse voltage: 80 V. Average rectified current per diode: 10 A. Forward voltage: 780 mV max at 10 A. Reverse leakage: 25 µA at 80 V. Junction temperature rated to 175 °C max. The 780 mV Vf at 10 A is typical for an 80 V Schottky in this current class — expect it to rise at higher junction temperatures, so derate the output current if the heatsink runs hot.","metaTitle":"STPS20SM80CFP Schottky Rectifier, 80V 20A Common Cathode","metaDescription":"STPS20SM80CFP dual Schottky rectifier, 80V reverse voltage, 10A per diode, 780mV Vf at 10A.
