The 16.7V minimum breakdown voltage gives a clean trigger threshold before the silicon starts conducting hard. ## DO-214AA footprint and temperature range The junction rating means derating applies above 25°C; at 150°C the peak pulse power drops per the datasheet curve, but for most 85°C-max designs the full 600W is available. For BOM planning that means no forced redesign window and no premium for end-of-life stock.","metaTitle":"STMicroelectronics SMBJ15A-TR TVS Diode, 600W","metaDescription":"STMicroelectronics SMBJ15A-TR TRANSIL™ TVS diode, 600W peak pulse power, 15V reverse standoff, unidirectional, 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":"SMBJ15","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)":"16.7V","Voltage - Clamping (Max) @ Ipp":"24.4V","Voltage - Reverse Standoff (Typ)":"15V","Current - Peak Pulse (10/1000µs)":"25.1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/28916e022258112f057e7568b7920d5a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMBJ15A-TR/alternatives.json"},"ai":{"faq":[{"question":"Is the SMBJ15A-TR unidirectional or bidirectional?","answer":"It is a unidirectional device — one channel, clamping in one polarity only.
