That simplifies board layout and reduces component count compared to placing two unidirectional TVS diodes back-to-back. The wide range also gives margin for self-heating during repetitive surge events — the junction temperature must stay under 150°C for reliable clamping. That means no imminent end-of-life risk for production BOMs — it remains a current, manufacturable part.","metaTitle":"STMicroelectronics SMBJ22CA-TR TVS Diode, 600W Bidirectional","metaDescription":"STMicroelectronics SMBJ22CA-TR bidirectional TVS diode, 600W peak pulse power, 22V standoff, 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":"SMBJ22","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)":"24.4V","Voltage - Clamping (Max) @ Ipp":"35.5V","Voltage - Reverse Standoff (Typ)":"22V","Current - Peak Pulse (10/1000µs)":"17.7A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/28916e022258112f057e7568b7920d5a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMBJ22CA-TR/alternatives.json"},"ai":{"faq":[{"question":"Is SMBJ22CA-TR bidirectional or unidirectional?","answer":"It is bidirectional — a single channel that clamps transients of either polarity.
