Help improve output voltage clamping – even when input voltage is high and diode currents are large. Our PolyZen devices are polymer-enhanced, precision Zener diode micro-assemblies. The advanced feature of these devices is that the Zener diode is thermally coupled to a resistively non-linear PPTC (Polymer Positive Temperature Coefficient) layer. This PPTC layer is fully integrated into the devices and is electrically in series between VIN and the diode-clamped VOUT. These offer resettable protection against multi-watt fault events without the need for multi-watt heat sinks. Use PolyZen devices to help protect low-power DC applications from damage caused by inductive voltage spikes, voltage transients, incorrect power supplies, and reverse bias. Features: Multi-Watt and Time Delayed Protection Overvoltage transient suppression Stable VZ vs. fault current Time delayed, overvoltage trip Time delayed, reverse bias trip Multi-Watt power handling capability Integrated device construction RoHS compliant Benefits: Stable Zener diode helps shield downstream electronics from overvoltage and reverse bias Trip events shut out overvoltage and reverse bias sources Analog nature of trip events helps minimize damage from upstream inductive spikes Minimal power dissipation requirements Single component placement
