Its 35 ns trr keeps the recovery spike short enough that a 100 kHz hard-switched boost stage doesn't need a snubber on the diode alone — the stored charge clears before the MOSFET turns back on. Forward drop is 3.6 V at the full 15 A rated current, so the conduction loss at that point is about 54 W; in practice the average current is lower, and the thermal design needs to pull heat out of the DOP3I-2 tab efficiently. ## Package and mounting — DOP3I-2 insulated tab That saves assembly time and keeps the thermal resistance consistent. The insulation rating matters for the 600 V working voltage: the creepage distance on the package body is designed for that rail, but the heatsink itself still needs to be at a safe potential or grounded per the system's insulation coordination. Mounting is straightforward with a screw through the tab hole; torque to the recommended value in the datasheet.","metaTitle":"STTH1506DPI Fast Recovery Diode, 600V 15A, 35ns trr, DOP3I-2","metaDescription":"STTH1506DPI fast recovery rectifier from STMicroelectronics: 600V, 15A average rectified current, 35ns reverse recovery time.","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":"Tube","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"DOP3I-2 Insulated (Straight Leads)","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH1506","Capacitance @ Vr, F":"-","Supplier Device Package":"DOP3I","Reverse Recovery Time (trr)":"35 ns","Current - Reverse Leakage @ Vr":"20 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"15A","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"3.6 V @ 15 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.5200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/be71bdb2b6046390a7b2d76f2398de2a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of the STTH1506DPI?","answer":"The reverse recovery time (trr) is 35 ns, which qualifies it as a fast recovery rectifier suitable for switching frequencies up to several hundred kilohertz in hard-switched topologies."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH1506DPI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH1506DPI when reusing this data.
