PolyZen CE Circuit Protection Devices

TE Connectivity's PolyZen CE series of circuit protection devices are ideal for portable consumer electronics

TE Connectivity's PolyZen CE Circuit Protection DevicesTE Connectivity's PolyZen CE (Consumer Electronics) series of circuit protection devices for tablet PCs and other portable consumer electronics is an extension of their current family. Consumer electronics require robust circuit protection to help protect sensitive electronics from overvoltage and overcurrent events that can result in costly product returns and warranty issues. The low-profile (1.0 mm height) PolyZen CE device, rated at an industry-leading 2.6 A, is an innovative solution that offers significant performance advantages over discrete solutions employing fuses, Zeners and other passive devices.

The PolyZen CE series offers board designers plug-and-play overvoltage protection devices that relieve them of the time it takes to integrate and test less effective discrete and more costly IC solutions. The PolyZen CE products integrate a precision Zener diode with 5.6 V and 13.2 V Zener voltage (Vz) options and a PolySwitch PPTC (Polymer Positive Temperature Coefficient) device in a single, surface-mount assembly. Offered in a compact, thin package useful for space-constrained applications, the PolyZen CE series uses a thermally-protected Zener diode to help shield downstream electronics against voltage transients, reverse bias, and the incorrect use of power supplies. The PolySwitch PPTC element shuts out excessive current while the fault condition remains and helps protect the Zener diode and downstream electronics from damage.
