Breakdown triggers at 25.7V minimum, and clamping holds at 37.5V — that 11.8V window between standoff and clamp absorbs load-dump and inductive kickback without letting the bus see destructive overvoltage. ## AEC-Q101 and the under-hood temperature envelope AEC-Q101 qualification means this part passed the full automotive stress battery — high-temperature reverse bias, temperature cycling, and ESD robustness. The 1500W rating assumes a standard FR-4 pad; a larger copper area improves derating at elevated ambient. ## Bidirectional — one part for both polarities Single bidirectional channel clamps equally in forward and reverse, so a single 1.5SMC27CAHR7G protects a 24V line that sees reverse-battery connection or an AC-coupled signal — no need for two back-to-back unidirectional parts. Zener-type construction gives sharp breakdown and low leakage below the standoff threshold. ## Sourcing and availability Supplied in Tape & Reel (TR) packaging for automated pick-and-place.","metaTitle":"1.5SMC27CAHR7G TVS Diode, 37.5V Clamp, DO-214AB, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5SMC27CAHR7G bidirectional Zener TVS, 1500W peak pulse, 23.1V standoff, 37.5V clamp, DO-214AB SMC, AEC-Q101 automotive.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Series":"Automotive, AEC-Q101, 1.5SMC","Package":"Tape & Reel (TR)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC27","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Voltage - Breakdown (Min)":"25.7V","Voltage - Clamping (Max) @ Ipp":"37.5V","Voltage - Reverse Standoff (Typ)":"23.1V","Current - Peak Pulse (10/1000µs)":"42A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC27CAHR7G/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does Taiwan Semiconductor provide for 1.5SMC27CAHR7G?","answer":"The part carries AEC-Q101 automotive qualification, which includes the full PPAP and reliability test data.
