The bidirectional single-channel configuration means it clamps both polarities equally — useful on AC signal lines or DC rails where reverse-voltage events are possible. The -55°C to 150°C junction temperature range covers outdoor telecom enclosures and under-hood automotive bays without derating the peak pulse capability at the cold end. ## DO-214AA SMB — board-fit and procurement Packaged in the DO-214AA (SMB) surface-mount footprint, the SMBJ43CA-13-F mates with standard SMB solder pads. The supplier device package is also SMB, so the land pattern is the same across the series. Tape & Reel and Cut Tape options let you order production reels or prototype quantities. Lifecycle status is Active — no NRND or EOL flag. The base product number SMBJ43 means the same die is available in unidirectional (SMBJ43A) if your design only needs single-polarity clamping.","metaTitle":"Diodes SMBJ43CA-13-F TVS Diode, 43V Standoff, 600W, DO-214AA","metaDescription":"Diodes Incorporated SMBJ43CA-13-F bidirectional Zener TVS, 43V reverse standoff, 69.4V clamp, 600W peak pulse, DO-214AA SMB.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diodes Incorporated","Type":"Zener","Series":"SMBJ","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":"SMBJ43","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMB","Voltage - Breakdown (Min)":"47.8V","Voltage - Clamping (Max) @ Ipp":"69.4V","Voltage - Reverse Standoff (Typ)":"43V","Current - Peak Pulse (10/1000µs)":"8.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/205f8bffce2c4a83c3c83b7d81a1413c.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/diodes-inc/SMBJ43CA-13-F","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/diodes-inc/SMBJ43CA-13-F when reusing this data.
