Zener-PPTC hybrids

25 February 2015 Circuit & System Protection

The PolyZen YC device series, now available from TE Connectivity, offers an integrated approach to help protect consumer electronics from damage caused by ESD (electrostatic discharge) and other electrical over-stress events that can lead to safety and warranty concerns. The new ZEN056V230A16YC and ZEN056V260A16YC combine a precision Zener diode and a resettable PolySwitch PPTC (polymer positive temperature coefficient) device in a 4,0 x 5,0 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 is able to simultaneously protect against damage from over-voltage, over-current, reverse bias, ESD and over-temperature events more effectively than solutions using multiple discrete devices.

The parts are suitable for enhancing reliability in sensitive electronics by offering up to 2,6 A hold current at room temperature.
