Its 75 ns reverse recovery time (trr) suits it for high-frequency rectification in power factor correction (PFC) stages, flyback converters, and snubber networks where switching losses must be contained. ## Parametric profile — leakage, forward drop, and thermal margin Reverse leakage is specified at 5 µA at the full 800 V blocking voltage, a low figure that helps maintain efficiency in offline supplies where leakage current contributes to standby power draw. Maximum forward voltage is 1.65 V at 2 A, a typical value for an 800 V-class fast recovery diode. Junction temperature is rated to 175°C maximum, giving headroom in enclosed power supplies or motor-drive environments where ambient temperatures push the thermal budget.","metaTitle":"STTH208RL Fast Recovery Diode, 800 V, 2 A, 75 ns trr, DO-15","metaDescription":"STTH208RL fast recovery diode: 800 V, 2 A, 75 ns trr, 5 µA leakage at 800 V, 175°C Tj.","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":"-","Package":"Tape & Reel (TR)","Diode Type":"Standard","Mounting Type":"Through Hole","Package / Case":"DO-204AC, DO-15, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH2","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-15","Reverse Recovery Time (trr)":"75 ns","Current - Reverse Leakage @ Vr":"5 µA @ 800 V","Voltage - DC Reverse (Vr) (Max)":"800 V","Current - Average Rectified (Io)":"2A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.65 V @ 2 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6a9cc33d8a439fb211acb372992c4978.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH208RL?","answer":"The reverse recovery time (trr) is 75 ns, making it suitable for fast-switching applications like PFC and flyback converters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH208RL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH208RL when reusing this data.
