Once a transient exceeds the breakdown threshold, the clamping voltage is held to a maximum of 10.5 V across the load. The 1.5 kW peak-pulse number is the standard TVS specmanship figure; the actual clamping voltage the downstream IC sees during a surge is 10.5 V maximum. ## AEC-Q101 and the 150 °C junction ceiling AEC-Q101 qualification means this part passed the automotive reliability stress suite — temperature cycling, high-temperature reverse bias, surge and ESD — at the wafer level. An ECU mounted near the engine block that hits 125°C ambient still has 25°C of junction margin above the case. The series name TransZorb® is Vishay's trademark for their glass-passivated die TVS construction — the glass passivation gives the junction better stability under repeated surge stress compared to an unpassivated Zener junction. ## DO-214AB SMC — assembly and board-fit context Surface-mount DO-214AB (SMC) lands on the board like any standard J-lead — reflow profile follows the paste and board stack-up, not the TVS itself. The Tape & Reel packaging suits high-volume assembly runs. The base product number 1.5SMC6.8 is the series anchor; the H, M3, and A/H suffixes carry the grade and packing variant — confirm the exact suffix against the BOM line before committing. No official Vishay cross-reference or pin-compatible successor is listed in the ledger for this exact order code.","metaTitle":"Vishay 1.5SMC6.8AHM3_A/H TVS Diode, 1500W Peak Pulse","metaDescription":"Vishay 1.5SMC6.8AHM3_A/H unidirectional Zener TVS, 5.8V standoff, 6.45V min breakdown, 1500W peak pulse.","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":"1.5SMC6.8","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)":"6.45V","Voltage - Clamping (Max) @ Ipp":"10.5V","Voltage - Reverse Standoff (Typ)":"5.8V","Current - Peak Pulse (10/1000µs)":"143A"}},"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/1.5SMC6.8AHM3_A%2FH/alternatives.json"},"ai":{"faq":[{"question":"What voltage does 1.5SMC6.8AHM3_A/H actually clamp at during a surge?","answer":"The standoff voltage is 5.8 V typical, and the minimum breakdown is 6.45 V."},{"question":"Is there a pin-compatible alternative in the 1.5SMC series?","answer":"The base product number 1.5SMC6.8 anchors this part to the 6.8 V standoff rating within the 1.5SMC series.
