The single unidirectional channel in the DO-214AA (SMB) surface-mount package fits standard pick-and-place and reflow assembly. The 25.7V minimum breakdown voltage sets the threshold where the diode starts conducting in avalanche. With a 23.1V reverse standoff voltage, this device protects a 24V nominal supply bus or a 23V regulated rail without conducting leakage current under normal operation. The 48.3V maximum clamp at the 83A peak pulse current (8/20 µs waveform) limits the voltage spike seen by downstream components during an ESD or load-dump event. That clamp voltage is the number your circuit designer uses to verify the input rating of the downstream DC-DC converter or linear regulator. ## AEC-Q101 qualification — what it buys you For a procurement decision, it removes the need for your quality team to qualify a non-automotive TVS for an automotive BOM line.","metaTitle":"STMicroelectronics SM6T27AY TVS Diode, AEC-Q101, 600W","metaDescription":"STMicroelectronics SM6T27AY automotive AEC-Q101 Zener TVS diode. 600W peak pulse power, 25.7V min breakdown, 23.1V standoff, DO-214AA SMB.","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":"SM6T27","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)":"25.7V","Voltage - Clamping (Max) @ Ipp":"48.3V","Voltage - Reverse Standoff (Typ)":"23.1V","Current - Peak Pulse (10/1000µs)":"83A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a95ac6513bab2f04fd61565540cbe6f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SM6T27AY/alternatives.json"},"ai":{"faq":[{"question":"Is the SM6T27AY AEC-Q101 qualified?","answer":"Yes, the SM6T27AY is AEC-Q101 qualified and belongs to the Automotive SM6TY series.
