31 polyzen devices 5 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. polyzen devices help provide resettable protection against damage caused by multi-watt fault events and require only 0.7w power dissipation. in the event of sustained high power conditions, the pptc element of the device trips to limit current and generate voltage drop. this functionality helps protect both the zener and the follow-on electronics, effectively increasing the diodes power handling capacity. ? helps shield downstream electronics from overvoltage and reverse bias ? trip events shut out overvoltage and reverse bias sources ? analog nature of trip events minimize upstream inductive spikes ? helps reduce design costs with single component placement and minimal heat sinking requirements ? rohs compliant ? overvoltage transient suppression ? hold currents up to 2.3a ? time delayed, overvoltage trip ? time delayed, reverse bias trip ? power handling on the order of 30 watts ? integrated device construction ? portable media players ? global positioning systems ? hard disk drives 5v & 12v bus ? solid state drives (ssd) 5v bus polyzen devices polymer protected zener diode benefits features applications ? cellphone charger port and usb power ? automotive peripheral input power ? dc power port protection ? industrial handheld pos obsolete not the latest revision
