This trr places it in the fast-recovery class (≤500 ns, >200 mA Io), making it suitable for high-frequency rectification in power supplies, PFC stages, and snubber circuits where switching losses and reverse-recovery current must be minimised. ## Parametric fit for the BOM line The 1.5 A average rectified current at 1 V forward drop (max) sets the conduction loss budget — at full load the forward dissipation is 1.5 W, which the DO-41 axial-lead package must sink through the lead length and PCB copper. The 3 µA reverse leakage at 200 V is low enough for standby power supplies and offline converters where off-state losses eat into efficiency targets. Junction temperature rating of 175°C (max) gives thermal headroom for high-ambient or confined enclosures, but the DO-41 through-hole package limits the heat path — a heatsink clip or extended PCB trace is needed to stay below Tj(max) at sustained 1.5 A. ## Obsolete — sourcing via independent distribution STMicroelectronics lists the STTH1R02RL as obsolete.","metaTitle":"STTH1R02RL Fast Recovery Diode, 200 V, 1.5 A, 30 ns trr","metaDescription":"STMicroelectronics STTH1R02RL fast recovery diode: 200 V, 1.5 A, 30 ns trr, DO-41 axial.","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) Cut Tape (CT)","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"DO-204AL, DO-41, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH1","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-41","Reverse Recovery Time (trr)":"30 ns","Current - Reverse Leakage @ Vr":"3 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Current - Average Rectified (Io)":"1.5A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"1 V @ 1.5 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a8dd7cd6af8fd75357262ef7e7a636fd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH1R02RL/alternatives.json"},"ai":{"faq":[{"question":"Is the STTH1R02RL obsolete?","answer":"Yes, STMicroelectronics has marked the STTH1R02RL as obsolete.
