Polymer Assemblies Protect Automotive Peripherals

For protecting automotive infotainment peripherals, i.e., global positioning systems, smart phones, game consoles, portable media players, etc., two additions to the PolyZen line of precision Zener diode micro-assemblies specify a higher hold current at 2.3A. The components employ a Zener diode for voltage clamping and a resistively non-linear, polymer positive temperature coefficient (PPTC) layer that responds to either diode heating or over current events by transitioning from a low to high resistance state. To shield downstream electronics from over voltage and reverse bias, they clamp and smooth inductive voltage spikes. Additionally, high-power absorption capabilities protect against faults that occur in the event of an incorrect or misconnected power supply. All PolyZen components are compatible with industry-standard installation procedures and available in tape-and-reel packaging. Pricing is $0.45 each/100,000. TYCO ELECTRONICS LTD., Menlo Park, CA.
