Its 35 ns reverse recovery time makes it suitable for high-frequency switching applications like power factor correction (PFC) circuits, freewheeling diodes in motor drives, and snubber networks in switch-mode power supplies. Packaged in a DO-214AA (SMB) surface-mount case, it fits standard reflow assembly processes. The 35 ns reverse recovery time is the key parameter for this diode. In a continuous-conduction-mode PFC boost stage, a slower diode would cause excessive turn-on loss in the MOSFET and higher EMI. The STTH3R06U's 35 ns trr keeps the recovery current spike short, letting the designer use a smaller snubber or even skip it in a well-laid-out 100 kHz design. The fast recovery characteristic is maintained across the full junction temperature range up to 175°C. ## Forward voltage and conduction loss budget At 1.7 V maximum forward drop at 3 A, the STTH3R06U's conduction loss runs about 5.1 W peak. That figure drives the thermal design: the DO-214AA package relies on the PCB copper for heat spreading. For continuous 3 A operation, a minimum 1 oz copper pad with thermal vias to an inner plane is recommended to keep the junction below 175°C.","metaTitle":"STTH3R06U Fast Recovery Diode, 600V 3A, 35ns trr","metaDescription":"STTH3R06U standard fast recovery diode from STMicroelectronics. 600V VR, 3A IF, 35ns trr in DO-214AA 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":"STTH3","Capacitance @ Vr, F":"-","Supplier Device Package":"SMB","Reverse Recovery Time (trr)":"35 ns","Current - Reverse Leakage @ Vr":"3 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"3A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.7 V @ 3 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2add2f39662fade4470c9fd66bcfefd8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH3R06U/alternatives.json"},"ai":{"faq":[{"question":"What is the reverse recovery time (trr) of STTH3R06U?","answer":"The reverse recovery time is 35 ns, making it 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/STTH3R06U","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH3R06U when reusing this data.
