Mounting is surface mount, supplied on Tape & Reel. ## What the voltage ratings mean for downstream protection The reverse standoff voltage of 6.4 V typ defines the bias the circuit applies during normal operation — above this the TVS begins to clamp. Selecting a TVS for an automotive 12 V rail, the standoff sits above the nominal battery voltage with headroom, and the clamping ceiling must stay below the absolute-max rating of whatever downstream IC sits behind it.","metaTitle":"Vishay 1.5SMC7.5CAHE3/9AT TVS Diode, 1.5 kW, 6.4 V, DO-214AB","metaDescription":"AEC-Q101 automotive TVS (TransZorb®), 1.5 kW peak pulse, 6.4 V standoff / 7.13 V breakdown / 11.3 V clamping at 133 A, DO-214AB SMC surface mount.","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%2F9AT/alternatives.json"},"ai":{"faq":[{"question":"What does the CA suffix mean on the 1.5SMC7.5CAHE3/9AT?","answer":"The CA suffix designates the bidirectional polarity variant of the 1.5SMC series. The base part number encodes the nominal standoff voltage (1.5SMC7.5 = 7.5 V class), and the CA bidirectional configuration is used on circuits where polarity reversal or AC-line clamping is a design requirement. The HE3/9A is a Vishay internal lot-traceability code — it does not affect the electrical rating or the selection decision."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC7.5CAHE3-9AT","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/1.5SMC7.5CAHE3-9AT when reusing this data.
