Zener TVS diode, 1.5SMCJ18AS_R1_00001, unidirectional, 18V standoff / 20V min breakdown / 29.2V clamping, 1.5 kW peak pulse, 51.4A (10/1000µs), DO-214AB SMC, surface mount, -55°C to 150°C junction, Tape & Reel / Cut Tape.","salesMarkdown":"The 1.5SMCJ18AS_R1_00001: The 18 V reverse standoff sets the maximum working voltage the protected rail can run at continuously without the TVS conducting — design the rail to sit below this in normal operation. When a surge arrives, the device breaks down at 20 V minimum and clamps the line at 29.2 V with a 51.4 A (10/1000 µs) surge applied — what the downstream IC actually sees is the clamped level, not the raw transient. This is a unidirectional Zener-type TVS, so it clamps positive transients only — reverse-polarity events are not suppressed. If the protected line sees bidirectional or negative surges, a different polarity configuration is required. ## Package, orientation, and sourcing posture Surface-mount SMC (DO-214AB) package — the cathode bar on the package body is the polarity reference; the marked side is cathode in the unidirectional configuration. Orientation is unambiguous on reflow, but a misplaced part will clamp in the wrong direction on a polarity-sensitive rail.","metaTitle":"Panjit 1.5SMCJ18AS_R1_00001 TVS Diode, 18V standoff","metaDescription":"Panjit 1.5SMCJ18AS_R1_00001 unidirectional Zener TVS diode, 18V standoff / 29.2V clamping, 1.5 kW peak pulse, DO-214AB SMC, -55 to 150°C junction.","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)","Base Product Number":"1.5SMC","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)":"20V","Voltage - Clamping (Max) @ Ipp":"29.2V","Voltage - Reverse Standoff (Typ)":"18V","Current - Peak Pulse (10/1000µs)":"51.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b8c6eab3232d925afed42f648094bb7c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMCJ18AS_R1_00001/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMCJ18AS_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/1.5SMCJ18AS_R1_00001 when reusing this data.
