Zener unidirectional TVS diode, 1.5SMCJ43AS_R1_00001, 1500W peak pulse, 43V reverse standoff, 69.4V clamping, 21.6A peak pulse, DO-214AB SMC surface mount, -55°C to 150°C.","salesMarkdown":"## 1.5 kW peak-pulse clamping — what the TVS ratings mean for the protection circuit The 1.5SMCJ43AS_R1_00001: The reverse standoff of 43 V defines the continuous working voltage the circuit can hold without conduction; the 47.8 V minimum breakdown marks where the Zener knee begins conducting; and the clamping voltage of 69.4 V at 21.6 A peak pulse sets the upper bound the downstream load sees during a surge event. For a 24 VDC rail, the 43 V standoff gives roughly a 1.7× headroom above the working voltage — enough to stay off during normal operation while clamping a IEC 61000-4-5 surge well below the protected semiconductor's abs-max rating. ## DO-214AB SMC — surface-mount protection in a compact power package The listed application is General Purpose — meaning it is not pinned to a single end-market spec but is broad enough to land in power supplies, motor drive snubbers, telecom rail protection, and instrumentation front-ends. The Power Line Protection field is marked No — this is a board-level clamp, not a field-replaceable mains protector, so the board designer handles the fusing and coordination upstream. Quoted to order through independent distribution against the BOM quantity; availability and lead time confirmed at RFQ. No franchised-only constraint flagged in the ledger, but traceable sourcing with date-code visibility is the standard ask when specifying a Zener TVS for a safety-adjacent or industrial control board.","metaTitle":"Panjit 1.5SMCJ43AS_R1_00001 TVS Diode, 43V, DO-214AB SMC","metaDescription":"Panjit 1.5SMCJ43AS_R1_00001 unidirectional Zener TVS diode, 1500W peak pulse, 43V standoff, DO-214AB SMC surface-mount package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Panjit International Inc.","Type":"Zener","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMC (DO-214AB)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"47.8V","Voltage - Clamping (Max) @ Ipp":"69.4V","Voltage - Reverse Standoff (Typ)":"43V","Current - Peak Pulse (10/1000µs)":"21.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b8c6eab3232d925afed42f648094bb7c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMCJ43AS_R1_00001/alternatives.json"},"ai":{"faq":[{"question":"Who supplies 1.5SMCJ43AS_R1_00001 and how is it quoted for volume purchases?","answer":"Sourced through independent distribution as a franchised and non-franchised line; availability and volume pricing confirmed at RFQ."},{"question":"What is the closest pin-compatible alternative to this TVS in the same SMC package?","answer":"Confirm the clamping voltage, peak pulse current, and junction temp grade against your protection budget before substituting; a 5 % standoff difference can shift the clamping ceiling enough to matter for sensitive downstream ICs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMCJ43AS_R1_00001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/panjit-international-inc/1.5SMCJ43AS_R1_00001 when reusing this data.
