The 'H' suffix on the base number 1.5SMC43 signals this AEC-Q101 variant; the standard-grade 1.5SMC43A shares the same electrical specs but lacks the automotive stress screening. The tape-and-reel packaging is the standard procurement format for automated pick-and-place assembly.","metaTitle":"1.5SMC43AH TVS Diode, 1500W, 36.8V Standoff, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5SMC43AH Zener TVS, 1500W peak pulse, 36.8V reverse standoff, 59.3V clamp, AEC-Q101 automotive grade.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Grade":"Automotive","Series":"1.5SMC","Package":"Tape & Reel (TR)","Applications":"Telecom","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC43","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"40.9V","Voltage - Clamping (Max) @ Ipp":"59.3V","Voltage - Reverse Standoff (Typ)":"36.8V","Current - Peak Pulse (10/1000µs)":"26A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2104","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8865ebcf8024f12ba614c78a4d777a7d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC43AH/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation is available for the 1.5SMC43AH?","answer":"As an AEC-Q101 qualified device, Taiwan Semiconductor Corporation provides the standard automotive PPAP documentation and a PCN (product change notification) process for any manufacturing changes.
