The clamping voltage at that current is 234 V max, so downstream components see no more than that across the protected rail. ## Electrical thresholds — standoff, breakdown, and clamping Reverse standoff voltage is 145 V — the rail voltage below which the diode is effectively open circuit. Breakdown voltage is guaranteed at 162 V min, so the device starts conducting between 162 V and the clamping voltage of 234 V. That 162-to-234 V window defines the protection zone: a 145 V nominal bus sees protection kicks in before the downstream 200 V-rated capacitors or FETs see an overvoltage. ## Surface-mount DO-214AB — footprint and assembly fit Housed in the standard DO-214AB (SMC) package, a JEDEC outline with a 0.050-inch gull-wing lead form. Tape-and-reel packaging suits automated pick-and-place for high-volume automotive lines. ## Active and available — sourcing reality Listed as Active.","metaTitle":"Vishay 1.5SMC170AHM3_A/H Zener TVS, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC170AHM3_A/H Zener TVS diode, 1500W peak pulse, 145V standoff, 234V clamp, DO-214AB, AEC-Q101 automotive qualified.","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":"1.5SMC170","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)":"162V","Voltage - Clamping (Max) @ Ipp":"234V","Voltage - Reverse Standoff (Typ)":"145V","Current - Peak Pulse (10/1000µs)":"6.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC170AHM3_A-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/1.5SMC170AHM3_A-H when reusing this data.
