At 11 V typical standoff, the rail can sit below 12.2 V without the device conducting; once a transient exceeds the 12.2 V minimum breakdown, the device enters avalanche and clamps the peak at 20.1 V maximum across the full 74.6 A peak pulse current window. ## 1500W peak pulse rating — sizing for the surge event Peak pulse current of 74.6 A is the current the clamping action forces through the TVS during a fault event. At 20.1 V clamping, 74.6 A delivers approximately 1.5 kW into the transient — the series impedance of the source, not the TVS, limits the actual peak. Budget the clamping voltage across your downstream load isolation as part of the total let-through energy calculation. Junction temperature range of -50°C to 150°C places this in the industrial and outdoor deployment class — the lower bound handles cold-store and outdoor-equipment starts; the upper bound covers junction operation in enclosed panels without forced cooling. At elevated ambient, derate the peak pulse power per the datasheet thermal curve; the 150°C absolute maximum is the trip-out ceiling, not a continuous operating point. ## Surface-mount DO-214AB — assembly and footprint context SMC/DO-214AB package with surface-mount termination accepts standard hot-air or IR rework profiles for this package class. The cathode band marks the anode-cathode polarity — this is a unidirectional device, so reverse-bias the cathode relative to the protected node. Strip packaging is typical for reel-free prototyping quantities or manual-reel assembly. Supplier device package is SMC/DO-214AB — electrically and mechanically identical to the JEDEC DO-214AB standard footprint, which means any compliant DO-214AB TVS in the same polarity and ratings class is a potential footprint match, though standoff and clamping values must be verified before substitution.","metaTitle":"1.5SMCJ11C TVS Diode, 11V Standoff, 1500W Peak Pulse","metaDescription":"Diotec 1.5SMCJ11C unidirectional TVS Zener in DO-214AB SMC. 11V standoff, 12.2V min breakdown, 20.1V clamping, 1500W peak pulse, -50°C to 150°C.","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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC/DO-214AB","Voltage - Breakdown (Min)":"12.2V","Voltage - Clamping (Max) @ Ipp":"20.1V","Voltage - Reverse Standoff (Typ)":"11V","Current - Peak Pulse (10/1000µs)":"74.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8068","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3fb0502b23c3703cafef426b7b2bf7e5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMCJ11C/alternatives.json"},"ai":{"faq":[{"question":"What package does 1.5SMCJ11C come in?","answer":"The device ships in the SMC/DO-214AB surface-mount package with strip packaging.
