The forward drop is 1.7 V at the full 1 A rated current, which is the typical conduction-loss trade-off for a 600 V fast-recovery part. ## SMB package — footprint and thermal reality The DO-214AA (SMB) package is a surface-mount footprint that fits standard reflow profiles. The reverse leakage is specified at 1 µA at the full 600 V blocking voltage — that is a room-temperature typical; expect it to climb with junction temperature, so budget the off-state loss in the thermal calculation for high-line operation.","metaTitle":"STTH1R06U Fast Recovery Diode, 600 V 1 A, 45 ns trr, SMB","metaDescription":"STTH1R06U is a 600 V, 1 A fast recovery rectifier with 45 ns trr in a surface-mount SMB package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Standard","Mounting Type":"Surface Mount","Package / Case":"DO-214AA, SMB","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH1","Capacitance @ Vr, F":"-","Supplier Device Package":"SMB","Reverse Recovery Time (trr)":"45 ns","Current - Reverse Leakage @ Vr":"1 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"1A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.7 V @ 1 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/06bbb223123f0c38be48d8898e0d18b7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH1R06U?","answer":"The reverse recovery time (trr) is 45 ns, which is the key spec that qualifies it as a fast recovery diode suitable for switching frequencies above 50 kHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH1R06U","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH1R06U when reusing this data.
