PolyZen YC Series Offers Integrated Protection for Consumer Electronics

The PolyZen YC device series now available from TE Connectivity's  Circuit Protection business unit offers an integrated approach to help protect consumer electronics, such as tablets, set-top boxes, hard disk drives and DC power ports, from damage caused by ESD (electrostatic discharge) and other electrical over-stress events that can lead to safety and warranty concerns. The new PolyZen ZEN056V230A16YC and ZEN056V260A16YC devices combine a precision Zener diode and a resettable PolySwitch PPTC (polymer positive temperature coefficient) device in a compact (4.0 mm x 5.0 mm x 1.2 mm) package. A PolyZen device's Zener diode is thermally connected to the PPTC device to enable rapid heat transfer, which in turn increases the PPTC device's reaction time. As a result, a single hybrid PolyZen YC device is able to simultaneously protect against damage from overvoltage, overcurrent, reverse-bias, ESD and overtemperature events more effectively than solutions using multiple discrete devices.

The PolyZen YC devices are suitable for enhancing reliability in sensitive electronics by offering up to 2.6 A hold-current at room temperature. They also provide high-performance ESD protection (±30kV) and overvoltage protection (8/20 microsecond pulse: 150 A) to help meet IEC standards (IEC 61000-4-2 and IEC 61000-4-5). One PolyZen YC device can help provide increased protection capabilities over typical discrete approaches that use fuses or PPTC, TVS (transient voltage suppression) or OVP (overvoltage protection) devices, either individually or combined.
