The three-voltage clamping hierarchy is what drives the selection decision: 6.4 V reverse standoff is the maximum operating voltage the diode leaks negligibly across; 7.13 V minimum breakdown is where it begins conducting; and 11.3 V is the maximum clamping voltage at the rated peak pulse current of 133 A. That 11.3 V ceiling is the figure that determines whether downstream ICs survive a defined surge event — the diode absorbs the transient and clamps the bus to this level. 1500 W peak pulse power rated at 10/1000 µs waveform means the device handles the slower, higher-energy transients typical of automotive load-dump and inductive kickback — not the ultra-fast ESD events that a dedicated ESD protection diode handles better. If your protection target is an ECU supply rail or CAN bus node, this is the part class you reach for. ## Why the automotive grade matters for under-hood deployment A commercial-grade SMC TVS without this rating has no documented margin for that envelope. For a 12 V automotive supply rail that can see load-dump transients up to 40 V before clamping, the standoff-to-breakdown spacing on this 6.4/7.13 V part is not a mismatch — the transient is higher, but the clamping event is brief enough that the diode absorbs it within its peak pulse rating. ## DO-214AB SMC package and automotive assembly The DO-214AB (SMC) package is the standard surface-mount outline for automotive power TVS diodes — the cathode bar on the top of the package identifies the polarity direction on the unidirectional variant, but the CA suffix confirms this part is bidirectional. Tape-and-reel packaging is standard for high-volume automotive assembly pick-and-place lines. The supplier device package is listed as SMCJ, which refers to the industry standard outline — the body dimensions are identical to DO-214AB, so land pattern and solder joint inspection criteria follow the JEDEC SMCJ footprint.","metaTitle":"Vishay 1.5SMC7.5CAHE3/57T Zener TVS Diode, 6.4 V Standoff","metaDescription":"Vishay 1.5SMC7.5CAHE3/57T bidirectional TVS diode, 6.4 V standoff / 7.13 V breakdown / 11.3 V clamping, 1500 W peak pulse, AEC-Q101, DO-214AB SMC, active.","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","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC7.5","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Voltage - Breakdown (Min)":"7.13V","Voltage - Clamping (Max) @ Ipp":"11.3V","Voltage - Reverse Standoff (Typ)":"6.4V","Current - Peak Pulse (10/1000µs)":"133A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC7.5CAHE3%2F57T/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 1.5SMC7.5CAHE3/57T and how do I get a price?","answer":"This part is available to quote against BOM quantities through independent distribution channels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC7.5CAHE3-57T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC7.5CAHE3-57T when reusing this data.
