No need to back-to-back two unidirectional diodes. STMicroelectronics lists the SMBJ43CA-TR as obsolete.","metaTitle":"SMBJ43CA-TR TRANSIL™ TVS Diode, 43V Standoff, 600W, DO-214AA","metaDescription":"SMBJ43CA-TR bidirectional Zener TVS diode, 43V reverse standoff, 600W peak pulse power, DO-214AA SMB package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"SMBJ, TRANSIL™","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AA, SMB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"SMBJ","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)":"-","Voltage - Clamping (Max) @ Ipp":"-","Voltage - Reverse Standoff (Typ)":"43V","Current - Peak Pulse (10/1000µs)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/28916e022258112f057e7568b7920d5a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMBJ43CA-TR/alternatives.json"},"ai":{"faq":[{"question":"Is SMBJ43CA-TR bidirectional?","answer":"Yes, it is a single bidirectional channel, clamping both positive and negative transients symmetrically."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SMBJ43CA-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SMBJ43CA-TR when reusing this data.
