Capacitance is 1435pF at 1MHz, so it loads the line but stays acceptable for low-speed power and signal lines. onsemi lists the P6SMB12AT3 as obsolete. For BOM continuity, the part is sourced through qualified independent distribution – we confirm traceability and date-code freshness per RFQ. The SMB package and unidirectional polarity are standard; confirm the mating footprint and orientation before committing.","metaTitle":"P6SMB12AT3 onsemi Zener TVS - 600W, AEC-Q101, DO-214AA","metaDescription":"P6SMB12AT3 onsemi Zener TVS diode, 600W peak pulse, 10.2V reverse standoff, AEC-Q101 automotive, DO-214AA SMB.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"onsemi","Type":"Zener","Series":"Automotive, AEC-Q101","Package":"Tape & Reel (TR)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AA, SMB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"P6SMB","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"1435pF @ 1MHz","Supplier Device Package":"SMB","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"11.4V","Voltage - Clamping (Max) @ Ipp":"16.7V","Voltage - Reverse Standoff (Typ)":"10.2V","Current - Peak Pulse (10/1000µs)":"36A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a8bfabecb7589ace8ca170560dd5f2f1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package and polarity does P6SMB12AT3 use?","answer":"It comes in a DO-214AA (SMB) surface-mount package, unidirectional (single-channel Zener).
