The 25 ns trr is the key parameter for reducing switching losses in hard-switched topologies like boost PFC and flyback converters. A faster recovery means less overlap between voltage and current during turn-off, which directly lowers the dissipation in the diode and the companion MOSFET. It also shrinks the snubber requirements — the recovery charge is small enough that a simple RC snubber across the diode often suffices, saving board space and component count. ## 8 A per diode — thermal reality in the DPAK Each diode in the common-cathode pair is rated for 8 A average rectified current. In a typical 12 V automotive alternator rectifier or a 48 V DC-DC output stage, that means the pair can handle up to 16 A total with proper thermal management. The DPAK package has an exposed tab on the drain side — the PCB copper area and via stitching under the tab determine the real-world current derating. At 175°C junction limit, expect to derate to roughly 60% of the 8 A if the ambient is 85°C and the copper area is minimal. The forward voltage drop of 1.1 V at 5 A is typical for a 200 V fast-recovery diode in this current class. ## AEC-Q101 and the automotive BOM The AEC-Q101 qualification is the automotive industry's stress-test standard for discrete semiconductors. It covers extended temperature cycling, high-temperature reverse bias, and humidity tests that commercial-grade parts skip. For a tier-1 supplier, using this part means no additional PPAP documentation or waiver request for the diode — it is already accepted in the supply chain. The active lifecycle status means ST is still manufacturing it, so no last-time-buy risk for ongoing production.","metaTitle":"STTH1002CBY-TR Automotive Fast Recovery Diode, 25 ns trr","metaDescription":"STMicroelectronics STTH1002CBY-TR is an AEC-Q101 qualified fast recovery diode, 200 V, 8 A per diode, 25 ns trr, in a DPAK package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Grade":"Automotive","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Technology":"Standard","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"TO-252-3, DPak (2 Leads + Tab), SC-63","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH1002","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"DPAK","Reverse Recovery Time (trr)":"25 ns","Current - Reverse Leakage @ Vr":"5 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Operating Temperature - Junction":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"1.1 V @ 5 A","Current - Average Rectified (Io) (per Diode)":"8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dc57de934c5591933f68530492ecc180.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STTH1002CBY-TR AEC-Q101 qualified?","answer":"Yes, the STTH1002CBY-TR carries AEC-Q101 qualification, making it suitable for automotive applications without additional qualification paperwork."},{"question":"What is the reverse recovery time of STTH1002CBY-TR?","answer":"The reverse recovery time (trr) is 25 ns, which is the key spec for fast-switching circuits like DC-DC converters and inverters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH1002CBY-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH1002CBY-TR when reusing this data.
