The 8 A average rating is the continuous forward current the part can carry with the tab soldered to adequate copper area. The 490 mV forward drop at 8 A drives conduction loss. ## Junction temperature and the thermal budget That 150°C ceiling is the hard limit — push past it and the leakage current climbs fast, especially on a 30 V Schottky where reverse leakage at rated Vr is already 1 mA at 25°C. In a 85°C ambient with the diode carrying 6 A, the junction will sit around 110-120°C depending on the board's thermal pad. That's fine for industrial or automotive under-hood use, but if the board is sealed in a hot enclosure, you'll want to measure the case temperature in the actual build. The DPAK (TO-252) footprint is standard — the tab is the cathode, and the two anode pins are tied together internally.","metaTitle":"STPS8L30BY-TR Schottky Diode, 30V 8A DPAK, 490mV Vf","metaDescription":"STPS8L30BY-TR Schottky rectifier: 30V reverse, 8A average, 490mV forward drop at 8A, DPAK surface mount, -40°C to 150°C junction.","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":"Tape & Reel (TR) Cut Tape (CT)","Technology":"Schottky","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS8","Capacitance @ Vr, F":"-","Supplier Device Package":"DPAK","Current - Reverse Leakage @ Vr":"1 mA @ 30 V","Voltage - DC Reverse (Vr) (Max)":"30 V","Current - Average Rectified (Io)":"8A","Operating Temperature - Junction":"-40°C ~ 150°C","Voltage - Forward (Vf) (Max) @ If":"490 mV @ 8 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3800","priceTiers":[{"qty":1,"price":"$1.38000","currency":"USD"},{"qty":10,"price":"$1.12800","currency":"USD"},{"qty":100,"price":"$0.87770","currency":"USD"},{"qty":500,"price":"$0.74392","currency":"USD"},{"qty":1000,"price":"$0.60601","currency":"USD"},{"qty":2500,"price":"$0.57048","currency":"USD"},{"qty":5000,"price":"$0.54332","currency":"USD"},{"qty":12500,"price":"$0.51824","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/412459be0f5e7a6f47d99c97c64daab4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS8L30BY-TR/alternatives.json"},"ai":{"faq":[{"question":"Is STPS8L30BY-TR RoHS compliant?","answer":"Yes, the STPS8L30BY-TR is listed as ROHS3 Compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS8L30BY-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS8L30BY-TR when reusing this data.
