ZEN132V075A48LS

It's time to enhance output voltage clamping, even when dealing with high input voltage and large diode currents. Enter product ZEN132V075A48LS. These advanced PolySwitch devices utilize polymer-enhanced, precision Zener diode micro-assemblies to achieve this goal. The key feature of these devices lies in the thermal coupling of the Zener diode to a resistively non-linear PPTC (Polymer Positive Temperature Coefficient) layer. This PPTC layer, fully integrated into the devices and electrically in series between VIN and the diode-clamped VOUT, provides resettable protection against multi-watt fault events without the need for multi-watt heat sinks. By using PolySwitch devices, you can protect low-power DC applications from damage caused by inductive voltage spikes, voltage transients, incorrect power supplies, and reverse bias
