Each diode is rated for an average rectified current of 20 A with a maximum forward voltage of 810 mV at that current — a reasonable conduction-loss figure for a 100 V Schottky. The pair shares the cathode tab, so the tab is at the output potential in a typical center-tap or OR-ing configuration. ## Conduction losses and thermal budget At 20 A per diode and 810 mV Vf, each die dissipates about 16.2 W in conduction. The D²PAK tab must be soldered to a generous copper plane — the junction temperature ceiling is 150 °C, and the 45 µA reverse leakage at 100 V doubles roughly every 10 °C above 25 °C, so keeping the tab below 110 °C is prudent to avoid thermal runaway in a high-voltage rail. ## Obsolete — sourcing via surplus and broker channels STMicroelectronics lists the STPS40SM100CG-TR as obsolete.","metaTitle":"STPS40SM100CG-TR Schottky Rectifier, 100V 20A Dual D²PAK","metaDescription":"STPS40SM100CG-TR dual common-cathode Schottky diode, 100 V, 20 A per diode, 810 mV Vf, 45 µA leakage.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS40","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D²PAK","Current - Reverse Leakage @ Vr":"45 µA @ 100 V","Voltage - DC Reverse (Vr) (Max)":"100 V","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"810 mV @ 20 A","Current - Average Rectified (Io) (per Diode)":"20A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/295145aada28569b4c01ba132d77235d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS40SM100CG-TR/alternatives.json"},"ai":{"faq":[{"question":"What are the specifications of STPS40SM100CG-TR?","answer":"It is a dual common-cathode Schottky rectifier rated at 100 V reverse voltage, 20 A average rectified current per diode, with a maximum forward voltage of 810 mV at 20 A.
