The part carries AEC-Q101 qualification, making it suitable for automotive electronic modules, engine-control units, and other vehicle-bus protection where the supplier must show the AEC-grade trace. Clamping voltage is 45.7 V at the 13.2 A peak-pulse current — the margin between the standoff rail and the clamp determines whether downstream ICs survive a load-dump or inductive kick. ## Obsolete — plan a replacement or last-time buy onsemi lists the P6SMB33CAT3 as Obsolete. For a BOM line that still needs the 33 V bidirectional rating in a DO-214AA SMB, the procurement desk should evaluate a last-time-buy window or a pin-compatible cross from a different onsemi P6SMB voltage code or an equivalent AEC-Q101 TVS from Vishay / Littelfuse / Bourns — the 28.2 V standoff and 45.7 V clamp are the matching targets. ## Package, mounting, and operating range Supplied in DO-214AA (SMB) surface-mount package. The junction temperature range is -65°C to 150°C — the wide span covers under-hood automotive and outdoor telecom enclosures where ambient can reach 105°C and the TVS self-heats during a pulse.","metaTitle":"P6SMB33CAT3 – onsemi Zener TVS, AEC-Q101, 600 W, DO-214AA","metaDescription":"onsemi P6SMB33CAT3 bidirectional Zener TVS, AEC-Q101 qualified, 600 W peak pulse, 28.2 V standoff, 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); 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","Bidirectional Channels":"1","Capacitance @ Frequency":"305pF @ 1MHz","Supplier Device Package":"SMB","Voltage - Breakdown (Min)":"31.4V","Voltage - Clamping (Max) @ Ipp":"45.7V","Voltage - Reverse Standoff (Typ)":"28.2V","Current - Peak Pulse (10/1000µs)":"13.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7982f44255cb5d90f9a69b1cf2fcf475.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the direct replacement for P6SMB33CAT3?","answer":"No official direct replacement MPN is published for the P6SMB33CAT3. For a pin-compatible alternative, look for a DO-214AA SMB, AEC-Q101-qualified, bidirectional Zener TVS with a 28.2 V standoff voltage and 45.7 V clamp at 13.2 A — these are the matching parametric targets.
