It clamps transients to 45.7V maximum at 13.2A peak pulse current (10/1000µs waveform), delivering 600W peak pulse power. For a 24V nominal supply (e.g., truck or industrial bus), this clamp is well above the rail, so the downstream DC/DC or load switch must survive that transient. The 585pF typical capacitance at 1MHz is moderate — fine for DC power lines but may load high-speed signal lines; for data interfaces, consider a lower-capacitance TVS. The 13.2A peak pulse current rating at 10/1000µs defines the surge withstand. In a 24V system with a 2-ohm source impedance, a 100V transient would push about 36A — this part would clamp but exceed its rating, so a higher-power TVS or series resistor may be needed. The 600W peak pulse power is the product of clamp voltage and current; derate for higher ambient temperature per the datasheet curve.","metaTitle":"P6SMB33AT3 onsemi Zener TVS Diode – 600W, 28.2V Standoff","metaDescription":"P6SMB33AT3 onsemi Zener TVS, 600W peak pulse, 28.2V reverse standoff, 31.4V breakdown, AEC-Q101 automotive grade, DO-214AA SMB package.","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":"585pF @ 1MHz","Supplier Device Package":"SMB","Unidirectional Channels":"1","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":"$0.6200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a8bfabecb7589ace8ca170560dd5f2f1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the breakdown and clamping voltage of P6SMB33AT3?","answer":"Minimum breakdown voltage is 31.4V.
