The standoff voltage sets the operating rail: at 11 V typical the part sits idle below its breakdown threshold on a nominal 12 V rail, then switches into avalanche at 12.2 V minimum. That 1.2 V spread between standoff and breakdown is the transient headroom before the TVS begins conducting. ## DO-214AB SMC for surface-mount board protection The DO-214AB SMC package is the standard SMT footprint for 1.5–3 kW bidirectional and unidirectional TVS diodes — the cathode bar on the sleeve identifies the polarity end, and the wide copper pad underneath the package tab carries the thermal path from the junction to the PCB copper for peak pulse dissipation. Junction temperature is rated from -50°C to 150°C, which covers industrial and outdoor environments where a TVS on an input rail can see cold start transients and thermal soak in the same service window. The 150°C ceiling constrains the peak pulse derating curve at elevated ambient. ## Active lifecycle — sourced to order The part is sourced to order through independent distribution and quoted against the BOM quantity at RFQ.","metaTitle":"1.5SMCJ11A TVS Diode, 1.5 kW Peak Pulse, 11 V Standoff","metaDescription":"Diotec 1.5SMCJ11A unidirectional Zener TVS diode, DO-214AB SMC package, 1500 W peak pulse at 10/1000 µs, 11 V reverse standoff, -50°C to 150°C junction.","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)":"12.2V","Voltage - Clamping (Max) @ Ipp":"18.2V","Voltage - Reverse Standoff (Typ)":"11V","Current - Peak Pulse (10/1000µs)":"82.4A"}},"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/1.5SMCJ11A/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 1.5SMCJ11A and how do I get a price?","answer":"Sourced through independent distribution — submit an RFQ for BOM quantity and the distributor will confirm pricing and lead time against the current order book.
