This is the part you specify when the protection diode must survive the same reliability screening as the ECU's main microcontroller. The active lifecycle status means no last-time-buy risk for current production programs. ## Package and footprint — DO-214AA SMB The bidirectional configuration means a single device replaces two series-connected unidirectional TVS diodes, saving board area. No power line protection feature — this is a signal or low-power rail clamp, not a mains-side suppressor.","metaTitle":"STMicroelectronics SM6T24CAY TVS Diode, 600W, AEC-Q101","metaDescription":"STMicroelectronics SM6T24CAY bidirectional Zener TVS diode, 600W peak pulse power, 20.5V standoff, AEC-Q101 qualified for automotive.","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":"SM6T24","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)":"22.8V","Voltage - Clamping (Max) @ Ipp":"42.8V","Voltage - Reverse Standoff (Typ)":"20.5V","Current - Peak Pulse (10/1000µs)":"93A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a95ac6513bab2f04fd61565540cbe6f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SM6T24CAY/alternatives.json"},"ai":{"faq":[{"question":"Can SM6T24CAY be used in automotive applications?","answer":"Yes.
