ZEN132V130A24LS

PTC 保护齐纳二极管The PolyZen LS series from TE Connectivity are polymer enhanced precision Zener diode micro-assemblies that aid in the protection of sensitive electronics from damage caused by inductive voltage spikes, voltage transients, incorrect power supply use and reverse bias. The TE Connectivity PolyZen LS series provide resettable protection against multi-watt fault event damage and require only 0.7W of power dissipation. Should a sustained high power condition occur, the PPTC element of the device will ’trip’ to limit current as well as generate a voltage drop. This functionality of the PolyZen LS series aids in the protection of both the Zener and the follow-on electronics - further increasing the diode’s power handling capacity.聚合体保护精密齐纳二极管微型组件，针对多功率故障情况提供可重置保护。 0.7W 功耗，无需任何特殊散热片。 相对稳定电压与 电流响应，有助于稳定输出电压，即使在输入电压和电源电流变化时。 延时，过电压跳闸 延时，反向流跳闸 100W 功率处理顺序 整体型设备结构 The PolyZen micro-assembly combines a Zener diode, enabling precise voltage clamping as well as a resistively non-linear, polymeric positive temperature coefficient PPTC layer that responds to either diode heating or overcurrent events by transitioning from a low to high resistive state. ### PolyZen 设备
