Its 75 ns reverse recovery time places it in the ultrafast class, making it a fit for continuous-current-mode (CCM) power factor correction boost stages, flyback snubbers, and output rectification in switching power supplies where recovery losses directly affect efficiency and thermal budget. ## Through-hole DO-201AD — board-level fit and thermal path The DO-201AD axial package is a through-hole form factor with a 9.5 mm body length and 1.3 mm lead diameter. It is intended for leaded insertion into plated through-holes on a PCB or point-to-point wiring on a terminal block. ## Junction temperature range and deployment environment The 175°C maximum junction allows headroom for derating when the diode is mounted near transformers or heatsinks that push local ambient above 85°C.","metaTitle":"STTH310 Diode, 1000V 3A Ultrafast Rectifier, DO-201AD","metaDescription":"STTH310 ultrafast rectifier diode: 75 ns trr, 1000 V reverse voltage, 3 A average current, DO-201AD axial 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":"Cut Tape (CT); Tape & Box (TB)","Diode Type":"Standard","Mounting Type":"Through Hole","Package / Case":"DO-201AD, Axial","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH310","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-201AD","Reverse Recovery Time (trr)":"75 ns","Current - Reverse Leakage @ Vr":"10 µA @ 1000 V","Voltage - DC Reverse (Vr) (Max)":"1000 V","Current - Average Rectified (Io)":"3A","Operating Temperature - Junction":"-40°C~175°C","Voltage - Forward (Vf) (Max) @ If":"1.7 V @ 3 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/708de5d293ae255b2b7febb88f6b0b28.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH310?","answer":"The STTH310 has a reverse recovery time (trr) of 75 ns, which qualifies it as an ultrafast rectifier suitable for high-frequency switching applications."},{"question":"Is STTH310 suitable for high voltage rectifier?","answer":"Yes, with a 1000 V maximum reverse voltage and 3 A average forward current, the STTH310 is suitable for high-voltage rectification in power supplies, PFC stages, and snubber circuits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH310","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH310 when reusing this data.
