The forward voltage drop is specified at 740 mV maximum at 10 A, and the junction can operate up to 175°C. This part is intended for high-frequency rectification, OR-ing diodes in redundant power supplies, and output rectification in switch-mode power converters where Schottky's low Vf and fast switching reduce conduction and recovery losses. ## Obsolete — sourcing this part now ## Package and mounting — TO-262 (I2PAK) through-hole The STPS20M80CR comes in a TO-262-3 package with long leads (I²Pak, TO-262AA), a through-hole power package designed for vertical mounting on a PCB or direct attachment to a heatsink. The three leads — anode 1, common cathode, anode 2 — match the standard footprint for a dual common-cathode Schottky in this outline. The through-hole format is straightforward for manual assembly or wave solder, but the part's MSL rating (not specified in the listing) should be verified before reflow if any rework is planned. The 175°C junction rating means this diode can handle high ambient temperatures in sealed enclosures or near hot power magnetics, provided the heatsinking keeps the case temperature within the derating curve.","metaTitle":"ST STPS20M80CR Schottky Rectifier, 80V 20A Common Cathode","metaDescription":"STPS20M80CR dual Schottky rectifier: 80V Vr, 10A per diode, 740mV Vf at 10A, 175°C Tj, TO-262 (I2PAK).
