In a 100 kHz PFC boost stage, that 35 ns trr keeps the switching loss low enough to avoid oversized heatsinks. ## 300 V, 10 A, 1.3 Vf — the operating envelope Rated 300 V reverse voltage and 10 A average forward current, with a maximum forward voltage of 1.3 V at 10 A. The 10 µA reverse leakage at 300 V is the standby-loss floor; junction temperature is rated to 175 °C max, so the thermal design must keep the die below that ceiling under full load. ## D2PAK footprint and rework The TO-263-3 / D2PAK surface-mount package has a large exposed copper tab on the bottom — the tab is the cathode and the primary thermal path. For rework, the hot-air profile needs to heat the tab through the board-side copper pour; a standard top-side nozzle alone may not wet the solder under the tab.","metaTitle":"STTH1003SG-TR Fast Recovery Diode, 300 V, 10 A, 35 ns trr","metaDescription":"STTH1003SG-TR: STMicroelectronics 300 V, 10 A fast recovery diode with 35 ns trr in D2PAK.","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":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH10","Capacitance @ Vr, F":"-","Supplier Device Package":"D2PAK","Reverse Recovery Time (trr)":"35 ns","Current - Reverse Leakage @ Vr":"10 µA @ 300 V","Voltage - DC Reverse (Vr) (Max)":"300 V","Current - Average Rectified (Io)":"10A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.3 V @ 10 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e6c9547aa309813b19296222ec0c93ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH1003SG-TR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH1003SG-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH1003SG-TR when reusing this data.
