This suits 36.8V nominal supply lines in automotive ECUs, battery management, and telecom rectifiers where the operating voltage sits below the standoff threshold. The tape-and-reel packaging supports automated pick-and-place for high-volume assembly. No power line protection feature is claimed — this is a pure transient suppressor, not a crowbar or overvoltage latch. ## Lifecycle and compliance The base product number 1.5SMC43 covers the unidirectional and bidirectional variants in this voltage class. The suffix HM3_A/I denotes the AEC-Q101 qualified, bidirectional, and the specific lead-free plating finish.","metaTitle":"Vishay 1.5SMC43CAHM3_A/I TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5SMC43CAHM3_A/I bidirectional TVS diode, 1500W peak pulse, AEC-Q101 qualified, 36.8V standoff, DO-214AB SMC package.","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":"1.5SMC43","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Voltage - Breakdown (Min)":"40.9V","Voltage - Clamping (Max) @ Ipp":"59.3V","Voltage - Reverse Standoff (Typ)":"36.8V","Current - Peak Pulse (10/1000µs)":"25.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5072","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC43CAHM3_A%2FI/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does Vishay provide for this part?","answer":"As an AEC-Q101 qualified device, Vishay provides a PPAP (Production Part Approval Process) package upon request, including the qualification test report, RoHS/REACH compliance declarations, and the device's PCN (process change notification) history.
