When a surge hits, it clamps at 42.1V maximum while shunting 14.9A of peak pulse current on the standard 10/1000µs waveform. ## DO-214AA SMB — field-swappable footprint The package is large enough to hand-solder with a fine-tip iron if you are doing rework on a bench, and small enough to fit tight layouts. No special pad geometry needed — the usual SMB land pattern works. No last-time-buy notice to track, no forced redesign for a drop-in replacement.","metaTitle":"STMicroelectronics SMBJ26CA-TR TVS Diode, 600W Bidirectional","metaDescription":"ST SMBJ26CA-TR bidirectional TVS diode, 26V reverse standoff, 28.9V breakdown, 42.1V clamp at 14.9A. 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":"SMBJ26","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)":"28.9V","Voltage - Clamping (Max) @ Ipp":"42.1V","Voltage - Reverse Standoff (Typ)":"26V","Current - Peak Pulse (10/1000µs)":"14.9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/28916e022258112f057e7568b7920d5a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMBJ26CA-TR/alternatives.json"},"ai":{"faq":[{"question":"Is SMBJ26CA-TR a bidirectional or unidirectional TVS diode?","answer":"It is bidirectional. The 'CA' suffix in SMBJ26CA-TR indicates a bidirectional device, clamping symmetrically in both directions. This is confirmed in the specification listing a single bidirectional channel."},{"question":"Can I use SMBJ26CA-TR in a 24V power supply application?","answer":"Yes. The 26V reverse standoff voltage means it will not conduct on a 24V DC rail during normal operation. The minimum breakdown voltage is 28.9V, giving a few volts of headroom before clamping starts. The maximum clamping voltage of 42.1V at 14.9A peak pulse current defines the protection envelope for transient events."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SMBJ26CA-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SMBJ26CA-TR when reusing this data.
