That means it passed the automotive-grade reliability stress sequence — temperature cycling, HAST, and high-temperature reverse bias — with PPAP documentation available for an OEM auditor. This is not an industrial part dressed as automotive; the AEC-Q101 mark is on the reel label and the datasheet. Packaged in DO-214AB (SMC), the body measures roughly 7.1 mm × 6.2 mm with a seated height around 2.6 mm — a standard footprint for 1500 W TVS diodes. Surface-mount assembly; the copper pad area under the cathode tab sets the RthJA, so the PCB layout determines how much steady-state power the part can dissipate before the junction hits 150°C. ## 185 V rail protection — clamping window and pulse handling The clamping factor — 328 V / 209 V = 1.57 — is tight for a 1500 W device, meaning the downstream components see less overvoltage stress per transient event. Rated 1500 W peak pulse power (1.5 kW) per the 10/1000 µs exponential waveform. Derate this figure above 25°C ambient per the datasheet curve — at 125°C the peak pulse power is roughly 60 % of the 25°C rating. The bidirectional configuration (single die, both polarities) means a single part clamps positive and negative transients without a series diode. ## Active production — sourcing for the BOM line Operating junction temperature range -65°C to 150°C covers the full automotive underhood temperature band — a grade-1 AEC-Q101 device, suitable for engine-bay and chassis-mount locations where ambient hits 105°C or higher.","metaTitle":"Vishay 1.5SMC220CAHM3_A/I Bidirectional TVS, 1500W, AEC-Q101","metaDescription":"Vishay 1.5SMC220CAHM3_A/I Zener TVS diode, 1500W peak pulse power, 185V reverse standoff, bidirectional, AEC-Q101 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":"1.5SMC220","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Voltage - Breakdown (Min)":"209V","Voltage - Clamping (Max) @ Ipp":"328V","Voltage - Reverse Standoff (Typ)":"185V","Current - Peak Pulse (10/1000µs)":"4.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4447","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7dd597f6fdc3f56660f78f3e5a960d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC220CAHM3_A%2FI/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does Vishay provide for the 1.5SMC220CAHM3_A/I?","answer":"As an AEC-Q101 qualified part, Vishay provides PPAP documentation (Production Part Approval Process) for automotive OEM audits.
