The gap between 64.1 V standoff and 71.3 V breakdown is the design headroom; the rail being protected should sit cleanly inside that window so the TVS never leaks appreciably in normal operation. The 150 °C ceiling gives thermal headroom above most automotive under-hood conditions, but the clamping energy and mounting thermal resistance still govern the actual Tj rise in a closed enclosure. ## AEC-Q101 qualification and automotive fit The series designation Automotive, AEC-Q101, 1.5SMC, TransZorb® places this part in the automotive-screened grade — the qualification covers temperature cycling, humidity, and surge testing to the AEC-Q101 stress levels. For an automotive ECU input or telecom rail feeding sensitive circuitry, the AEC-Q101 badge is the signal that the lot traceability and production part approval process meet the automotive OEM standard, not just the commercial screening pass/fail. ## Package and sourcing posture The DO-214AB (SMC) package is the standard JEDEC footprint for the 1.5SMC series — surface-mount reflow, tape-and-reel packing. The part carries the base product number 1.5SMC75, which is the identifier to use when cross-checking against alternate distributors or checking second-source availability within the same Vishay series footprint.","metaTitle":"Vishay 1.5SMC75AHM3_A/H, AEC-Q101 TVS Zener, 1.5kW","metaDescription":"Active AEC-Q101 TVS Zener from Vishay General Semiconductor — 1.5kW peak pulse, 104V clamping, DO-214AB SMC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"Automotive, AEC-Q101, 1.5SMC, TransZorb®","Package":"Tape & Reel (TR)","Applications":"Automotive, Telecom","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC75","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"71.3V","Voltage - Clamping (Max) @ Ipp":"104V","Voltage - Reverse Standoff (Typ)":"64.1V","Current - Peak Pulse (10/1000µs)":"14.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3331","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I source the 1.5SMC75AHM3_A/H and what is the typical lead time?","answer":"The base product number 1.5SMC75 identifies the series footprint if you are evaluating second-source or cross-reference options within the Vishay 1.5SMC family."},{"question":"What does the AEC-Q101 qualification mean for my design compared to a standard 1.5SMC part?","answer":"The AEC-Q101 stress qualification applies increased temperature cycling, humidity bias, and surge testing beyond the commercial-grade screening, with mandatory lot traceability and PPAP documentation — automotive ECUs and telecom infrastructure equipment requiring AEC-Q qualify the part, not a standard Zener with the same standoff voltage."},{"question":"Is the 1.5SMC75AHM3_A/H unidirectional or bidirectional?","answer":"The part is a single unidirectional channel — it protects a positive-going transient on one polarity rail only.
