TE Circuit Protection, a business unit of TE Connectivity, 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 (1.0mm-height) PolyZen CE device, rated at 2.6A, is a solution that offers significant performance advantages over discrete solutions employing fuses, Zeners and other passive devices, according to TE. 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.
PolyZen products integrate a precision Zener diode, with 5.6V and 13.2V 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.
“When building circuit protection into tablets and other cutting-edge consumer products, manufacturers must weigh component costs against the high price of potential warranty returns that can ultimately compromise their brand,” said Curtis Wong, Global Portfolio Product Manager for TE Circuit Protection. “The two conventional approaches either provide inadequate protection or are less cost effective. Multiple discrete component solutions, such as fuses and TVS diodes, generally don’t offer enough overvoltage protection, and ICs, with their unnecessary ‘bells-and-whistles’ features, and are more costly. In contrast, our new PolyZen CE series hits the sweet spot of value-to-performance by offering a single placement, cost-effective solution that provides reliable, robust overvoltage and overcurrent protection for a wide variety of portable electronics applications.”
The PolyZen CE series includes six devices with various current ratings to accommodate a wide range of applications from Tablets to GPS and navigation systems to HDDs and portable media players and set top boxes.
