The reverse standoff voltage of 14 V defines the working rail it sits across — the clamping ceiling of 25.8 V at peak pulse current sets the maximum stress the protected circuit sees when a surge fires. The minimum breakdown of 15.6 V sits above the 14 V standoff, giving enough headroom that the device stays off during normal operation while responding fast enough to catch the event — the band between 14 V and 15.6 V is the guard zone. ## Package and thermal headroom The DO-214AB SMC package is the standard surface-mount footprint for 1.5 kW TVS diodes; it ships on strip for automated placement in panel or DIN-rail enclosure assemblies. Junction temperature is rated to 150°C with a floor of -50°C, giving wide margin for designs that run hot or see outdoor thermal cycling — a 1.5 kW TVS absorbing a surge event dissipates significant energy in a short pulse, and that thermal headroom matters.","metaTitle":"Diotec 1.5SMCJ14C TVS diode, 14V standoff, 1.5kW peak pulse","metaDescription":"Diotec 1.5SMCJ14C unidirectional Zener TVS in DO-214AB, 14V standoff, 1.5kW peak pulse, 58.1A peak pulse current.
