The 8.55V reverse standoff voltage and 18.6V clamping at 215A peak pulse current (8/20µs) make it a fit for protecting 5V and 12V rails in automotive ECUs, sensors, and infotainment modules against load-dump and inductive-switching transients. ## Bidirectional — no polarity guesswork on site This is a single bidirectional channel, so orientation does not matter when you solder it in — handy if you are swapping a blown TVS on a field-returned board without a schematic. The DO-214AA body is small enough for tight layouts but still hand-solderable with a fine iron tip. No power line protection means it is designed for signal or low-power supply clamping, not mains.","metaTitle":"STMicro SM6T10CAY TVS Diode, 600W Bidirectional, AEC-Q101","metaDescription":"STMicroelectronics SM6T10CAY bidirectional TVS diode, 600W peak pulse, 8.55V 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":"SM6T10","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMB (DO-214AA)","Voltage - Breakdown (Min)":"9.5V","Voltage - Clamping (Max) @ Ipp":"18.6V","Voltage - Reverse Standoff (Typ)":"8.55V","Current - Peak Pulse (10/1000µs)":"215A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a95ac6513bab2f04fd61565540cbe6f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to SM6T10CAY?","answer":"The base product number SM6T10 covers multiple variants in the SM6TY series — the SM6T10CAY is the bidirectional AEC-Q101 version. A unidirectional AEC-Q101 sibling (SM6T10AY) exists but is not pin-compatible for bidirectional applications since the polarity marking differs. For a non-automotive bidirectional replacement, the SM6T10CA (without the Y suffix) is the commercial-grade equivalent, same package and ratings."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SM6T10CAY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SM6T10CAY when reusing this data.
