TE Connectivity unveils integrated overvoltage and overcurrent devices for consumer electronics

August 28, 2012 // By Paul Buckley
TE Circuit Protection, a business unit of TE Connectivity Ltd. has introduced the PolyZen CE (Consumer Electronics) series of circuit protection devices for tablet PCs and other portable consumer electronics.

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.

TE Circuit Protection’s PolyZen products integrate a precision Zener diode, with 5.6 V and 13.2 V Zener voltage (Vz) options, and a PolySwitch PPTC (Polymeric Positive Temperature Coefficient) device in a single, surface-mount assembly. Offered in a thin, compact package useful for space-constrained applications, the PolyZen CE series uses a thermally protected Zener diode to help protect 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 shield the Zener diode and downstream electronics from damage.

The PolyZen CE series includes six devices with various current ratings to accommodate a wide range of applications. These include:   Tablet PCs and Ultrabooks;  GPS and navigation systems;  Hard disk drives (HDDs);  Solid state drives (SSDs);  Cigarette lighter adaptor chargers;  Cell phone charger ports and USB power;  Portable media players and set top boxes;  Automotive infotainment power;  DC power port and Industrial handheld point-of-sale (POS) products.

Availability     

Samples of the PolyZen CE series are available now and priced at $0.66 each for minimum quantities of 4,000 units.
