The recovery is soft enough to keep EMI under control without a large series snubber resistor — a real advantage when board space in an ECU module is measured in square centimetres. That is a deliberate trade-off: the higher Vf buys the fast recovery and the 175°C junction rating. In a 1 A continuous circuit the conduction loss is about 1.9 W at full load — the SOD-128 flat package's thermal pad needs a decent copper pour on the PCB to keep the junction below 150°C in a 105°C ambient.","metaTitle":"STTH1R06AFY 600V 1A Fast Recovery Diode, AEC-Q101, 45 ns trr","metaDescription":"STTH1R06AFY automotive fast recovery diode: 600 V, 1 A, 45 ns trr, AEC-Q101, SOD-128 flat.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Grade":"Automotive","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Technology":"Standard","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"SOD-128","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH1","Capacitance @ Vr, F":"-","Supplier Device Package":"SOD128Flat","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":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"1.9 V @ 1 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4700","priceTiers":[{"qty":1,"price":"$0.50000","currency":"USD"},{"qty":10,"price":"$0.42800","currency":"USD"},{"qty":100,"price":"$0.31970","currency":"USD"},{"qty":500,"price":"$0.25118","currency":"USD"},{"qty":1000,"price":"$0.19409","currency":"USD"},{"qty":3000,"price":"$0.18673","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9522258a1dda51de75dd03fc3b34d99f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH1R06AFY/alternatives.json"},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH1R06AFY?","answer":"The reverse recovery time (trr) is 45 ns, measured at the rated forward current and reverse voltage conditions typical for fast-recovery diodes in this voltage class."},{"question":"Can STTH1R06AFY replace STTH1R06?","answer":"The STTH1R06AFY is the automotive-qualified (AEC-Q101) variant of the STTH1R06 base product. The electrical ratings — 600 V, 1 A, 45 ns trr — are the same. The package differs: the AFY suffix uses the SOD-128 flat package, while the base STTH1R06 typically comes in SMA or SMB. If your board footprint is designed for SOD-128, the AFY variant is a direct drop-in replacement with the added automotive qualification."},{"question":"What is STTH1R06AFY's listed grade?","answer":"The part is listed as Automotive grade and is qualified to AEC-Q101, which covers the stress tests and reliability requirements for automotive electronic components."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH1R06AFY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH1R06AFY when reusing this data.
