Once it clamps, the 25.8V maximum clamping voltage at 58.1A peak pulse is what the protected load actually sees. The 1500W peak pulse rating (10/1000 µs waveform) is the surge energy ceiling; a TVS that sees repeated transients above that rating wears out the junction. For a board-level protection scheme the standoff must sit above the normal operating rail with headroom, and the clamping voltage must stay below the absolute-max input of whatever IC sits behind it. ## DO-214AB SMC package — standard footprint, one thermal thing to watch Operating junction temperature runs from -50°C to 150°C. The 150°C ceiling is the limiting factor in confined enclosures with poor airflow — a TVS under a heatsink or inside a sealed housing will run hotter than the ambient reading suggests, and the surge derating curve must be applied at the actual local temperature, not room temperature. General-purpose application rating means this part is not qualified to any automotive or industrial safety standard — it carries no AEC-Q qualification and no IEC 62368 fire-safety test report. For consumer electronics, telecom infrastructure, or industrial control boards where there is no regulatory requirement for a standards-certified protection component, it fills the BOM slot. If the end equipment requires a UL 497A-listed protector or an IEC 61000-4-2 tested component, this part does not satisfy that requirement on its own — the circuit-level compliance test result depends on the full board layout and surrounding components. Unidirectional only — the single polarity channel means it clamps positive transients but offers no protection against negative going below ground. For lines that see bidirectional stress you need a dual-directional TVS or two unidirectional devices back-to-back.","metaTitle":"Diotec 1.5SMCJ14 TVS Diode, 14V Standoff, DO-214AB","metaDescription":"Diotec 1.5SMCJ14 unidirectional TVS diode, 14V standoff, 25.8V clamping at 58.1A, 1500W peak pulse, DO-214AB SMC surface mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diotec Semiconductor","Type":"Zener","Series":"-","Package":"Strip","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":"-50°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":"25.8V","Voltage - Reverse Standoff (Typ)":"14V","Current - Peak Pulse (10/1000µs)":"58.1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9158","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3fb0502b23c3703cafef426b7b2bf7e5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMCJ14/alternatives.json"},"ai":{"faq":[{"question":"Who supplies 1.5SMCJ14 and how is it quoted for volume purchases?","answer":"Diotec Semiconductor is the brand of record.
