The wide temperature margin means derating for ambient heat is less of a concern than with commercial-grade parts. For dual-sourcing, the SMBJ36A (unidirectional) shares the same breakdown and clamping specs but protects only one polarity; the SMBJ36CA is the bidirectional variant.","metaTitle":"STMicroelectronics SMBJ36CA-TR TVS Diode, 600W","metaDescription":"ST SMBJ36CA-TR bidirectional TVS diode: 36V standoff, 40V breakdown, 58.1V clamp at 10.3A, 600W peak pulse power, DO-214AA SMB.","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":"SMBJ36","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)":"40V","Voltage - Clamping (Max) @ Ipp":"58.1V","Voltage - Reverse Standoff (Typ)":"36V","Current - Peak Pulse (10/1000µs)":"10.3A"}},"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/SMBJ36CA-TR/alternatives.json"},"ai":{"faq":[{"question":"Is SMBJ36CA-TR a bidirectional TVS diode?","answer":"Yes — it has one bidirectional channel, so it clamps transients of either polarity symmetrically.
