Peak pulse power is rated at 600 W for a 10/1000 µs waveform, with a clamping voltage of 21.2 V at the peak pulse current of 28 A. The single unidirectional channel handles positive-going surges; for bidirectional protection you need two devices or a different part number. onsemi lists the P6SMB15AT3 as Obsolete. For BOM lines that still call out this exact order code, the only sourcing path is through independent distributors or the open market — we can quote against your quantity and verify date code and traceability before shipment. ## Package and temperature range for the rework bench The SMB footprint is shared with many other P6SMB-series devices, so a replacement with the same package and similar electricals can drop in without a board spin.","metaTitle":"P6SMB15AT3 onsemi Zener TVS Diode – Obsolete, AEC-Q101, 600W","metaDescription":"P6SMB15AT3 onsemi Zener TVS diode, AEC-Q101, 600W peak pulse, 12.8V standoff, DO-214AA.","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); Cut Tape (CT)","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":"1175pF @ 1MHz","Supplier Device Package":"SMB","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"14.3V","Voltage - Clamping (Max) @ Ipp":"21.2V","Voltage - Reverse Standoff (Typ)":"12.8V","Current - Peak Pulse (10/1000µs)":"28A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a8bfabecb7589ace8ca170560dd5f2f1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to P6SMB15AT3?","answer":"Any P6SMB-series Zener TVS in the same DO-214AA package with a 12.8 V standoff voltage is a direct footprint match.
