It is a unidirectional device in a DO-214AA (SMB) surface-mount package, rated for a 5.8V reverse standoff voltage and a 13.4V clamping maximum at the peak pulse current. ## AEC-Q101 grade — why it matters for the BOM ## Sourcing reality — active, no LTB risk The base product number SM6T6 covers the family; the Y suffix denotes the automotive grade. ## Clamping voltage and standoff — the protection window With a 5.8V reverse standoff voltage, this Zener sits on a 5V or 6V rail without conducting in normal operation. The 13.4V clamping maximum at the 8/20µs pulse current limits the voltage seen by the protected IC during a surge event. The 600W peak-pulse rating at 10/1000µs defines the energy-handling capability — enough for automotive load-dump and inductive kickback scenarios.","metaTitle":"STMicroelectronics SM6T6V8AY Zener Diode, 600W, AEC-Q101","metaDescription":"STMicroelectronics SM6T6V8AY Zener diode, 600W peak pulse, 5.8V standoff, AEC-Q101 automotive grade.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"Automotive, AEC-Q101, SM6TY, TRANSIL™","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AA, SMB","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"SM6T6","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMB (DO-214AA)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"6.45V","Voltage - Clamping (Max) @ Ipp":"13.4V","Voltage - Reverse Standoff (Typ)":"5.8V","Current - Peak Pulse (10/1000µs)":"298A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a95ac6513bab2f04fd61565540cbe6f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SM6T6V8AY/alternatives.json"},"ai":{"faq":[{"question":"Is SM6T6V8AY automotive qualified AEC-Q101?","answer":"Yes, the SM6T6V8AY is part of the Automotive, AEC-Q101 series.
