Its 600 W peak pulse power rating (10/1000 µs waveform) translates to an 11.8 A peak pulse current capability, with clamping held to 53.3 V maximum at that current. For a general-purpose protection diode, this power level covers the majority of industrial and telecom transient events — motor drive inductive kicks, hot-swap surges, and secondary lightning protection — without needing a larger footprint device. ## Package and assembly fit No power line protection feature is built in — this is a unidirectional clamp for signal or DC rail protection, not an AC line suppressor.","metaTitle":"SMBJ33A-TR TVS Diode, 33V Standoff, 600W Peak Pulse","metaDescription":"STMicroelectronics SMBJ33A-TR unidirectional TVS diode, 33V reverse standoff, 600W peak pulse power, DO-214AA SMB package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"SMBJ, TRANSIL™","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AA, SMB","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"SMBJ33","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)":"36.7V","Voltage - Clamping (Max) @ Ipp":"53.3V","Voltage - Reverse Standoff (Typ)":"33V","Current - Peak Pulse (10/1000µs)":"11.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/28916e022258112f057e7568b7920d5a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMBJ33A-TR/alternatives.json"},"ai":{"faq":[{"question":"Is SMBJ33A-TR equivalent to SMBJ33A?","answer":"Yes, SMBJ33A-TR is electrically identical to the base SMBJ33A — same 33 V standoff, same 600 W peak pulse rating, same DO-214AA package.
