www.DataSheet4U.com PolyZen Devices PolyZen Devices Polymer Protected Zener Diode PolyZen devices are polymer enhanced precision Zener diode micro-assemblies that help protect sensitive electronics from damage caused by inductive voltage spikes, voltage transients, use of incorrect power supplies and reverse bias. The PolyZen micro-assembly incorporates a stable Zener diode for precise voltage clamping and 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 resistance state. 4 PolyZen devices help provide resettable protection against damage caused by multi-watt fault events and require only 0.7W power dissipation.
