The 60 V reverse voltage rating and 645 mV forward drop at 10 A per diode make it a fit for 48 V bus OR-ing, output rectification in switch-mode supplies, and freewheeling diodes in motor drives where the Schottky's low Vf and fast recovery (≤500 ns above 200 mA) reduce switching losses compared to a standard PN junction. ## Sourcing an obsolete dual Schottky No official successor is recorded, so the replacement search should focus on a pin-compatible common-cathode Schottky in TO-220-3 with matching 60 V / 10 A per diode ratings. ## Thermal and leakage — the real-world limits Junction temperature is capped at 150 °C max — the TO-220 tab needs a heatsink sized for the total power dissipation of both diodes at the load current. Reverse leakage is 40 µA at 60 V and 25 °C, but rises exponentially with junction temperature; above 100 °C the leakage current can dominate the thermal budget, so the heatsink design should keep the junction well below the 150 °C ceiling under continuous load.","metaTitle":"STPS20SM60CT Schottky Diode, 60V 10A Common Cathode","metaDescription":"STPS20SM60CT dual Schottky rectifier, 60V reverse, 10A per diode, common cathode in TO-220-3.

This is the standard pinout for a dual Schottky in TO-220-3."},{"question":"What is a direct replacement for STPS20SM60CT?","answer":"No official replacement is recorded by STMicroelectronics. A pin-compatible substitute must be a common-cathode Schottky in TO-220-3 rated for at least 60 V and 10 A per diode.
