The common-cathode pair lets one TO-220 replace two discrete Schottkies, saving board area and reducing the pick-and-place count by one. The through-hole TO-220 suits point-of-load stages where thermal vias and copper pour carry the junction heat to a heatsink or chassis. ## Forward drop and reverse leakage — the thermal budget drivers At 20 A forward current the maximum forward voltage is 920 mV. The 8 µA reverse leakage at 150 V rated voltage is low enough to keep stand-by dissipation negligible, but leakage rises exponentially with junction temperature — the 175°C absolute maximum junction rating means the heatsink design must keep Tj well below that ceiling under peak load.","metaTitle":"STPS40150CT Schottky diode, 150 V 20 A","metaDescription":"STPS40150CT Schottky diode array, 150 V reverse voltage, 20 A per diode, common-cathode pair in TO-220.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS40150","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","Current - Reverse Leakage @ Vr":"8 µA @ 150 V","Voltage - DC Reverse (Vr) (Max)":"150 V","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"920 mV @ 20 A","Current - Average Rectified (Io) (per Diode)":"20A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9800","priceTiers":[{"qty":1,"price":"$1.98000","currency":"USD"},{"qty":10,"price":"$1.64600","currency":"USD"},{"qty":100,"price":"$1.31010","currency":"USD"},{"qty":500,"price":"$1.10856","currency":"USD"},{"qty":1000,"price":"$0.94059","currency":"USD"},{"qty":2000,"price":"$0.89357","currency":"USD"},{"qty":5000,"price":"$0.85997","currency":"USD"},{"qty":10000,"price":"$0.83150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5c74a81d7e6450da086f818982ab34c8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS40150CT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS40150CT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS40150CT when reusing this data.
