The fast recovery characteristic is mandatory. ## 600 V / 3 A — the power-stage fit Rated for 600 V DC reverse voltage and 3 A average forward current, this diode fits secondary-side rectification in off-line AC-DC converters. The 1.3 V forward voltage at 3 A sets conduction loss that drives the thermal design around the DPAK package. ## DPAK footprint and mounting The STTH3L06B-TR comes in a TO-252-3 / DPAK surface-mount package, two leads plus the tab. The part ships on Tape & Reel, consistent with automated pick-and-place assembly. No special handling beyond standard MSL precautions applies — the DPAK is a mature, widely used power package.","metaTitle":"STTH3L06B-TR Fast Recovery Diode, 600V 3A DPAK, 85ns trr","metaDescription":"STMicroelectronics STTH3L06B-TR 600V 3A standard fast recovery diode in DPAK package. 85ns trr, 1.3V Vf at 3A.","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)","Diode Type":"Standard","Mounting Type":"Surface Mount","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH3L","Capacitance @ Vr, F":"-","Supplier Device Package":"DPAK","Reverse Recovery Time (trr)":"85 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":"1.3 V @ 3 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9bc27b3ea0b236aa7ff4abe41acd7105.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH3L06B-TR/alternatives.json"},"ai":{"faq":[{"question":"What is the exact replacement for STTH3L06B-TR?","answer":"STMicroelectronics has not published an official successor order code for the STTH3L06B-TR in the available lifecycle records. Because the part is obsolete, the replacement path depends on the specific application requirements: a functionally equivalent 600 V 3 A fast recovery diode in DPAK with 85 ns or faster trr from the same or another manufacturer would be the starting point for a cross-reference search. The STTH3L06B-TR uses a standard DPAK footprint, so pin-compatible alternatives from ON Semiconductor (MUR series) or ST's own STTH3L06 variants in the same package are worth evaluating a"},{"question":"Is STTH3L06B-TR obsolete?","answer":"Yes, the STTH3L06B-TR carries an obsolete lifecycle status. No further factory production is planned. Buyers should verify date codes and authenticity when procuring from the open market."},{"question":"Can STTH3L06B-TR be replaced by a standard diode or must it be fast recovery?","answer":"It must be a fast recovery diode. The 85 ns reverse recovery time is the defining characteristic — a standard 50/60 Hz rectifier diode with microsecond-range trr would overheat and fail in any switching converter application this part was designed for. The fast recovery rating of ≤500 ns at >200 mA is the minimum trr class; the actual 85 ns part is well inside that window. Substituting a standard diode is not viable in any circuit running above a few hundred hertz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH3L06B-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH3L06B-TR when reusing this data.
