Its 13 V reverse standoff voltage means it stays transparent below that level. The minimum breakdown voltage of 14.4 V ensures the device does not conduct until the rail rises above regulation tolerance. ## 600 W pulse — what the surge rating buys you The clamping voltage maxes out at 21.5 V while carrying 29 A of peak pulse current. That 21.5 V ceiling tells you the downstream components — capacitors, regulators, the IC itself — need a voltage rating comfortably above that level. A 25 V rated MLCC on the rail would be marginal; 35 V or higher gives the headroom a reliability review expects. ## DO-214AA (SMB) — footprint and thermal path Housed in a DO-214AA (SMB) package for surface-mount assembly, the SMBJ13A-TR occupies a standard footprint shared across the SMBJ family. The SMB body dissipates pulse energy through the board copper.","metaTitle":"STMicroelectronics SMBJ13A-TR TVS Diode, 600W, 13V Standoff","metaDescription":"STMicroelectronics SMBJ13A-TR unidirectional TVS diode. 13V reverse standoff, 14.4V min breakdown, 21.5V clamping, 600W peak pulse power.","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":"SMBJ13","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)":"14.4V","Voltage - Clamping (Max) @ Ipp":"21.5V","Voltage - Reverse Standoff (Typ)":"13V","Current - Peak Pulse (10/1000µs)":"29A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/28916e022258112f057e7568b7920d5a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMBJ13A-TR/alternatives.json"},"ai":{"faq":[{"question":"Can I replace SMBJ13A with SMBJ13A-TR?","answer":"Yes.

The two are functionally interchangeable."},{"question":"What is the difference between SMBJ13A-TR and SMBJ13CA-TR?","answer":"The SMBJ13A-TR is a unidirectional TVS diode, clamping transients in one polarity. The SMBJ13CA-TR is a bidirectional device, clamping both positive and negative transients. For a single-ended 12 V rail referenced to ground, the unidirectional SMBJ13A-TR is the correct choice. For AC signal lines or bipolar supplies, use the bidirectional variant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SMBJ13A-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SMBJ13A-TR when reusing this data.
