The minimum breakdown voltage is 77.8V, which gives a guard band above the 70V reverse standoff. The 113V maximum clamping voltage tells you the highest voltage the protected circuit will see during a pulse — ensure downstream components (caps, ICs) have a voltage rating above that level. The 5.5A peak pulse current rating (10/1000 µs) is the current the diode can sink while clamping; paired with the 600W peak pulse power, this defines the surge capability. For longer or higher-energy events, you may need to parallel devices or step up to a higher-power series.","metaTitle":"SMBJ70CA-TR Bidirectional TVS Diode, 600W, 70V Standoff","metaDescription":"STMicroelectronics SMBJ70CA-TR bidirectional TVS diode, 600W peak pulse, 70V reverse standoff, DO-214AA.","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":"SMBJ70","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMB (DO-214AA)","Voltage - Breakdown (Min)":"77.8V","Voltage - Clamping (Max) @ Ipp":"113V","Voltage - Reverse Standoff (Typ)":"70V","Current - Peak Pulse (10/1000µs)":"5.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/28916e022258112f057e7568b7920d5a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMBJ70CA-TR/alternatives.json"},"ai":{"faq":[{"question":"Is SMBJ70CA-TR bidirectional or unidirectional?","answer":"It is a bidirectional device — one channel that clamps both positive and negative transients symmetrically.
