That 37.5V clamp ceiling sits well below the typical 40V abs-max rating of downstream 24V automotive ECUs, so a single this part per protected line keeps the bus within the silicon's safe operating area during load-dump or inductive kickback events. ## Automotive qualification and what it buys you AEC-Q101 qualification means this part passed the full automotive stress battery: temperature cycling, high-temperature reverse bias, and ESD robustness per the JEDEC-based automotive discrete standard. ## DO-214AB SMC footprint and board integration The DO-214AB (SMC) package is the larger of the common SMC footprints — the body measures roughly 7.1mm x 6.1mm with a 2.6mm height. The cathode band is marked on the body; the anode is the opposite end. The copper pad area under the package directly sets the thermal impedance for the 1500W pulse — a 1oz copper pour of at least 30mm² per terminal is typical for the full rated peak pulse power. This is a unidirectional Zener TVS (single channel), so the cathode goes to the protected rail and the anode to ground. The part has no power-line protection feature — it is designed for signal and low-power supply lines, not mains or high-current bus protection.","metaTitle":"Vishay 1.5SMC27AHM3_A/I TVS, 1500W, DO-214AB, AEC-Q101","metaDescription":"Vishay 1.5SMC27AHM3_A/I Zener TVS diode, 1500W peak pulse, 23.1V standoff, 37.5V clamp, DO-214AB, AEC-Q101 automotive qualified.","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":"1.5SMC27","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)":"25.7V","Voltage - Clamping (Max) @ Ipp":"37.5V","Voltage - Reverse Standoff (Typ)":"23.1V","Current - Peak Pulse (10/1000µs)":"40A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3331","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC27AHM3_A%2FI/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation is available 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.
