The minimum breakdown voltage is 20.9 V, where the device starts to avalanche. Under a peak pulse current of 102 A (8/20 µs waveform), the clamping voltage is limited to 30.6 V — this is the maximum voltage the downstream circuitry sees during the transient event. With a peak pulse power rating of 600 W (10/1000 µs waveform), this part handles the energy from typical load-dump and inductive-load switching transients on 12 V and 24 V automotive power rails. ## Lifecycle and compliance for BOM planning It is AEC-Q101 qualified, which means the PPAP documentation and part-per-million defect rate controls are available for automotive OEM submissions. The base product number is SM6T22, and the 'Y' suffix denotes the automotive-grade qualification.","metaTitle":"STMicroelectronics SM6T22AY TVS Diode, AEC-Q101, 600W","metaDescription":"STMicroelectronics SM6T22AY automotive AEC-Q101 qualified TVS diode, 18.8V standoff, 20.9V breakdown, 30.6V clamping, 600W peak pulse power, 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":"SM6T22","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)":"20.9V","Voltage - Clamping (Max) @ Ipp":"30.6V","Voltage - Reverse Standoff (Typ)":"18.8V","Current - Peak Pulse (10/1000µs)":"102A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a95ac6513bab2f04fd61565540cbe6f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SM6T22AY/alternatives.json"},"ai":{"faq":[{"question":"Is SM6T22AY AEC-Q101 qualified?","answer":"Yes, the SM6T22AY is part of the Automotive, AEC-Q101, SM6TY, TRANSIL™ series, making it qualified for automotive applications with the associated PPAP documentation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SM6T22AY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SM6T22AY when reusing this data.
