The junction temperature ceiling is 125 °C, so the thermal path through the TO-220AC tab to a heatsink governs the real-world current derating. ## Obsolete — no official successor listed No direct replacement order code appears on the official record, so a new-design BOM should not rely on this part. The TO-220AC footprint is common across many 20 A Schottky diodes, so a parametric search for a 15 V, 20 A Schottky in TO-220AC will yield several active alternatives from ST and other manufacturers. ## Through-hole TO-220AC — mounting and thermal note The STPS20L15D comes in a TO-220-2 package (ST's TO-220AC variant), with through-hole leads for board mounting. The package ships in Tube form, which is typical for through-hole power devices.","metaTitle":"STPS20L15D Schottky Diode, 15V 20A TO-220AC, Obsolete","metaDescription":"STPS20L15D Schottky rectifier: 15V reverse, 20A average, 410 mV Vf at 19 A, TO-220AC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-2","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS20","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220AC","Current - Reverse Leakage @ Vr":"6 mA @ 15 V","Voltage - DC Reverse (Vr) (Max)":"15 V","Current - Average Rectified (Io)":"20A","Operating Temperature - Junction":"125°C (Max)","Voltage - Forward (Vf) (Max) @ If":"410 mV @ 19 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6200","priceTiers":[{"qty":1,"price":"$2.62000","currency":"USD"},{"qty":10,"price":"$2.17800","currency":"USD"},{"qty":100,"price":"$1.73380","currency":"USD"},{"qty":500,"price":"$1.46702","currency":"USD"},{"qty":1000,"price":"$1.24474","currency":"USD"},{"qty":2000,"price":"$1.18251","currency":"USD"},{"qty":5000,"price":"$1.13805","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9f7e289b9e39e17a6d1f0c811a7693d2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS20L15D/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy STPS20L15D available via RFQ confirmation?","answer":"The STPS20L15D is obsolete and not in active factory production."},{"question":"What is a suitable replacement for STPS20L15D?","answer":"No official successor is listed by STMicroelectronics.
