Zener TVS diode, 1.5SMCJ14AS_R1_00001, unidirectional, 14V reverse standoff, 15.6V breakdown, 23.2V clamping, 64.7A peak pulse, 1500W peak pulse power, DO-214AB SMC, -55°C to 150°C junction, Surface Mount, Tape & Reel / Cut Tape.","salesMarkdown":"## What the 14V standoff and clamping ratings mean The 1.5SMCJ14AS_R1_00001: The 14V reverse standoff is the working voltage — the TVS stays off and draws only leakage current up to this level, presenting a high impedance to the protected line. That clamping ceiling, not the standoff, determines whether downstream silicon survives the event. ## Peak pulse power and the 1500W rating The 1.5 kW rating is the key differentiator from lower-power TVS families — it handles the larger energy dump from inductive kick, motor coil collapse, or ESD at system level, not just board-level whacks. The DO-214AB (SMC) package thermal impedance is sized for this power level; the cathode tab must mount to a solid copper pad on the PCB to realise the rated pulse capability. ## Unidirectional Zener TVS — polarity and circuit context This is a unidirectional clamp, so it protects against positive-going transients in one polarity only — it behaves as a forward-biased diode below ground in the reverse direction, passing through a typical 0.7 V forward drop. For bidirectional protection or AC lines the Panjit family offers the corresponding bidirectional variant. The part is classified for general-purpose applications per the evidence; it does not carry a power-line-protection certification, which would be required for direct AC-mains protection without an intermediate impedance.","metaTitle":"1.5SMCJ14AS_R1_00001 TVS Diode, 14V Standoff, DO-214AB SMC","metaDescription":"Panjit 1.5SMCJ14AS_R1_00001 unidirectional Zener TVS diode, 1500W peak pulse, 14V standoff / 23.2V clamping, DO-214AB SMC, Active.","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)":"15.6V","Voltage - Clamping (Max) @ Ipp":"23.2V","Voltage - Reverse Standoff (Typ)":"14V","Current - Peak Pulse (10/1000µs)":"64.7A"}},"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/1.5SMCJ14AS_R1_00001/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between a Zener TVS and a standard Zener diode for clamping?","answer":"A Zener TVS like the 1.5SMCJ14AS_R1_00001 is designed to absorb a defined peak pulse energy within a specified voltage window — 15.6V breakdown minimum to 23.2V clamping maximum at 64.7A peak current on a 10/1000 µs waveform.
