The AEC-Q101 qualification and 175°C maximum junction temperature target it for automotive on-board charger PFC stages, DC-DC converter boost diodes, and motor-drive freewheeling clamps where the board temperature runs high and the voltage bus exceeds 800 V. ## 105 ns trr at 15 A — recovery charge and switching loss Reverse recovery time is 105 ns at 15 A, which places it in the fast-recovery class for a 1200 V silicon diode. At 50-80 kHz hard switching the recovery charge is low enough to keep the turn-off loss within the D²PAK's thermal budget when the tab is soldered to a 2-3 cm² copper island on a 2 oz board. Above 100 kHz the stored charge starts to dominate — a SiC Schottky would cut the switching loss further, but the STTH1512GY-TR avoids the SiC price premium for most automotive power stages. ## Forward drop and leakage at temperature Maximum forward voltage is 1.9 V at 15 A and 25°C junction. At 150°C the Vf typically drops 10-15% while the reverse leakage rises — the datasheet specifies 15 µA at 1200 V and 25°C, but the leakage doubles roughly every 10°C above 100°C. The 175°C Tj(max) gives headroom for transient overloads, but continuous operation near the 15 A limit at high ambient requires the tab to be thermally coupled to the PCB or a heatsink. ## Active production, AEC-Q101 traceability The AEC-Q101 qualification means the lot is traceable through the production-PPAP documentation that automotive Tier-1 buyers require. The -GY suffix is the automotive-grade variant of the base STTH1512 die; the marking, the test flow, and the temperature cycling limits differ from the commercial-grade STTH1512G.","metaTitle":"STTH1512GY-TR 1200V 15A Fast Recovery Diode, AEC-Q101, D2PAK","metaDescription":"STTH1512GY-TR: 1200V 15A standard fast recovery diode, 105 ns trr, AEC-Q101 automotive grade, D2PAK surface mount.","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":"Automotive, AEC-Q101","Package":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Standard","Mounting Type":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH1512","Capacitance @ Vr, F":"-","Supplier Device Package":"D²PAK","Reverse Recovery Time (trr)":"105 ns","Current - Reverse Leakage @ Vr":"15 µA @ 1200 V","Voltage - DC Reverse (Vr) (Max)":"1200 V","Current - Average Rectified (Io)":"15A","Operating Temperature - Junction":"-40°C~175°C","Voltage - Forward (Vf) (Max) @ If":"1.9 V @ 15 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3100d12ee32d8435a5d02b7f0175f66c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can STTH1512GY-TR replace the base STTH1512 or STTH1512G in an existing design?","answer":"Yes — the STTH1512GY-TR uses the same STTH1512 die in the same D²PAK footprint (TO-263AB). The difference is the AEC-Q101 automotive qualification: the -GY variant adds the extended temperature cycling, lot traceability, and PPAP-level documentation that the commercial-grade STTH1512G does not carry. If the BOM already specifies the commercial part and the application is not automotive, the -GY will work electrically but costs more. If the design is automotive, the -GY is the correct grade."},{"question":"What is the closest pin-compatible alternative if STTH1512GY-TR is unavailable?","answer":"The base STTH1512G (commercial-grade, same D²PAK) is the closest pin-compatible alternative — same die, same footprint, same electrical ratings. The difference is the AEC-Q101 qualification: the -G variant lacks the automotive-grade test flow and lot traceability. For a non-automotive BOM the -G is a direct drop-in. For an automotive line, the -GY should be sourced through the authorized channel to maintain the qualification chain."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH1512GY-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH1512GY-TR when reusing this data.
