The reverse standoff voltage is 145V, with a minimum breakdown of 162V. For a 145V nominal DC rail — common in automotive 24V systems after a boost stage or in telecom rectifier outputs — this part sits below the rail voltage during normal operation and only conducts when a transient pushes the line above 162V. ## Package and board-fit — DO-214AB footprint, reflow profile The DO-214AB (SMC) package is a surface-mount form factor with a cathode band for polarity identification. The supplier device package is the same DO-214AB (SMC) — no sub-variant. The mounting type is surface mount, compatible with standard reflow soldering profiles. The package footprint is shared across the 1.5SMC series, so a single PCB land pattern serves the full voltage range from 5V to 188V. Power line protection is marked as No — this is a TVS for DC rail clamping, not for AC mains. The unidirectional configuration means it protects one polarity; for bipolar rails, two parts or a bidirectional variant would be needed.","metaTitle":"Vishay 1.5SMC170AHM3/I TVS, 1500W, 145V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC170AHM3/I Zener TVS diode, 1500W peak pulse power, 145V reverse standoff, AEC-Q101 qualified, DO-214AB SMC package.","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":"1.5SMC170","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":[{"question":"What compliance documentation does Vishay provide for 1.5SMC170AHM3/I?","answer":"The part is AEC-Q101 qualified for automotive applications.
