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.
