When a transient exceeds the breakdown voltage (162 V min), the Zener clamps at 234 V max, shunting up to 6.4 A of peak pulse current. The 1500 W peak pulse rating means the diode absorbs the transient energy without exceeding the junction temperature limit — a key parameter for selecting the right TVS for a given surge waveform. The AEC-Q101 qualification includes temperature cycling, high-temperature reverse bias, and ESD sensitivity testing per the automotive stress criteria. This part is intended for 12 V, 24 V, and 48 V automotive bus protection where the nominal rail voltage stays below 145 V.","metaTitle":"Vishay 1.5SMC170AHE3/9AT TVS Diode, 1500W, AEC-Q101","metaDescription":"Vishay 1.5SMC170AHE3/9AT Zener TVS diode, 1500W peak pulse, 145V standoff, 234V clamp, 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","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 (SMCJ)","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":"Is the 1.5SMC170AHE3/9AT AEC-Q101 qualified?","answer":"Yes, it is part of Vishay's Automotive AEC-Q101 series, making it suitable for automotive applications requiring the stress and reliability testing per AEC-Q101."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC170AHE3-9AT","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/1.5SMC170AHE3-9AT when reusing this data.
