The 14.5 V maximum clamping voltage at 690 A (8/20 µs) means downstream components on a 6.4 V supply rail see a hard voltage ceiling during a surge event. For a 12 V automotive battery line, the 6.4 V reverse standoff voltage is intentionally lower than the nominal rail to provide margin — this part is designed for a regulated 6.4 V bus, not direct battery connection. The 1500 W peak pulse rating (10/1000 µs) ensures the device can absorb repetitive transients typical of inductive load switching without derating below the junction temperature limit. ## AEC-Q101 qualification and automotive deployment AEC-Q101 qualification means the SM15T7V5CAY has passed stress tests for temperature cycling, moisture resistance, and high-temperature reverse bias that commercial TVS parts skip. No power line protection is built in — this is a signal or low-power rail protector, not a mains-side suppressor. For production BOM lines requiring an AEC-Q101 bidirectional TVS in the SMC footprint, this part is specified into new designs without LTB risk. The base product number SM15T7V5 covers the unidirectional variant (SM15T7V5A) and the bidirectional 'CAY suffix seen here — the 'CAY is the bidirectional, AEC-Q101 version.","metaTitle":"SM15T7V5CAY bidirectional TVS diode, 1500W, AEC-Q101, SMC","metaDescription":"STMicroelectronics SM15T7V5CAY bidirectional Zener TVS, 1500W peak pulse power, 6.4V standoff, AEC-Q101 qualified, DO-214AB SMC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"Automotive, AEC-Q101, SM15TY, TRANSIL™","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"SM15T7V5","Operating Temperature":"-40°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC","Voltage - Breakdown (Min)":"7.13V","Voltage - Clamping (Max) @ Ipp":"14.5V","Voltage - Reverse Standoff (Typ)":"6.4V","Current - Peak Pulse (10/1000µs)":"690A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d3caa9efa0f4fede168088411f4832fd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SM15T7V5CAY RoHS compliant?","answer":"The part is listed as part of the SM15TY series which is manufactured in a RoHS-compliant process, though no explicit RoHS statement is carried in this record.
