Rated 1500 W peak pulse (10/1000 µs waveform), the 11.3 V clamping voltage ceiling is the let-through voltage the protected circuit sees when a surge fires — this is the clamping ceiling, not the clamping action voltage, so the downstream MOSFET gate or bus input must be rated above 11.3 V. The reverse standoff of 6.4 V sets the working DC voltage the diode blocks continuously; the minimum breakdown of 7.13 V means it does not clamp below that threshold in normal operation. ## Peak pulse current, temperature, and package — the ratings that drive BOM fit Junction operating temperature of -65 °C to +150 °C covers the automotive under-hood band — an ECU mounted near the engine bay in a summer idling condition typically sees 125 °C local ambient; the 150 °C TJ rating provides margin before thermal derating activates. DO-214AB (SMC) surface-mount package with Tape & Reel packaging — the cathode band marks the unidirectional polarity direction; the device is not a power-line protector (power line protection is listed No), so it is correctly deployed as a secondary clamp on a signal or low-current rail, not across the main power bus.","metaTitle":"Vishay 1.5SMC7.5AHM3/H, AEC-Q101 TVS Diode, 11.3V Clamping","metaDescription":"Vishay 1.5SMC7.5AHM3/H — AEC-Q101 qualified unidirectional Zener/TVS, 1500 W peak pulse, 11.3 V max clamping, 133 A peak pulse (10/1000 µs), DO-214AB SMC.","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","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","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Unidirectional Channels":"1","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/1.5SMC7.5AHM3%2FH/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation is available for the 1.5SMC7.5AHM3/H?","answer":"The part is from the Vishay General Semiconductor catalogue and carries the AEC-Q101 automotive qualification; specific REACH, RoHS, or UL documentation should be confirmed against the manufacturer's current product datasheet at the time of order."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC7.5AHM3-H","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/1.5SMC7.5AHM3-H when reusing this data.
