The forward voltage drop is 950 mV maximum at 30 A, which sets the conduction loss at full load. This is a key input for the thermal budget when heatsinking the TO-220 tab. The part carries the ECOPACK2 series designation, indicating ST's lead-free and RoHS-compliant package finish. No AEC-Q automotive qualification is listed in the record. ## Reverse leakage and junction temperature limits Reverse leakage current is 275 µA at the rated 120 V reverse voltage. The maximum junction temperature is 150°C, which is the ceiling for the TO-220 package's thermal performance when bolted to a heatsink.","metaTitle":"STPS30SM120ST Schottky Diode 30A 120V TO-220 Obsolete","metaDescription":"STPS30SM120ST Schottky rectifier, 30 A average, 120 V reverse, 950 mV Vf at 30 A, TO-220-3.","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":"ECOPACK®2","Package":"Tube","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS30","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220","Current - Reverse Leakage @ Vr":"275 µA @ 120 V","Voltage - DC Reverse (Vr) (Max)":"120 V","Current - Average Rectified (Io)":"30A","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"950 mV @ 30 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eef385b549afb33e0a48d397691a4a2d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS30SM120ST/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS30SM120ST","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS30SM120ST when reusing this data.
