Its 80 ns reverse recovery time places it in the fast-recovery class — not ultrafast, but fast enough to cut switching losses in continuous-conduction-mode PFC boost stages and flyback snubbers where a standard recovery diode would overheat. The 1.3 V forward drop at 1 A is typical for this voltage and speed class; the 1 µA reverse leakage at the full 600 V rating gives confidence in high-temperature idle conditions. A 175 °C maximum junction temperature provides thermal headroom for compact designs where the SMA body has limited copper to sink heat. ST lists the STTH1L06A as Active. The base product number STTH1 covers a family of voltage and speed variants; the L06A suffix identifies the 600 V, 1 A, 80 ns trr option. ## SMA package — board-area reality The DO-214AC (SMA) footprint is a common two-pad SMD outline shared across many 1 A rectifiers. The junction-to-ambient thermal resistance depends heavily on the PCB copper area; the 175 °C Tj rating gives margin, but the designer should still size the pad and via array for the expected average current and ambient temperature. No exposed pad here — the junction relies on the leadframe and solder joints for heat extraction.","metaTitle":"STTH1L06A Fast Recovery Diode, 600 V 1 A, 80 ns trr, SMA","metaDescription":"STTH1L06A 600 V 1 A fast recovery rectifier in DO-214AC SMA. 80 ns trr, 1.3 Vf at 1 A, 175 °C Tj.","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-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH1","Capacitance @ Vr, F":"-","Supplier Device Package":"SMA","Reverse Recovery Time (trr)":"80 ns","Current - Reverse Leakage @ Vr":"1 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"1A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.3 V @ 1 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/87e22011b04a534e9b12df7a44c2ff20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH1L06A?","answer":"The STTH1L06A has a reverse recovery time (trr) of 80 ns. This is the fast-recovery class — suitable for switching frequencies where a standard recovery diode would cause excessive turn-off losses, but not as fast as an ultrafast diode in the 20–35 ns range."},{"question":"What is the closest pin-compatible alternative to STTH1L06A?","answer":"The STTH1L06A is a standard STMicroelectronics fast-recovery diode in the DO-214AC (SMA) package. Many 600 V, 1 A fast-recovery diodes share the same SMA footprint — for example, the STTH1R06A (same package, 30 ns trr) or the STTH1L06 (same die, different packaging suffix). The exact trr and Vf trade-off depends on the application; the L06A's 80 ns trr is a middle-speed option in the STTH1 family. No single drop-in equivalent is listed as a formal cross, but the SMA footprint is widely second-sourced across manufacturers."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH1L06A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH1L06A when reusing this data.
