TE Connectivity PolyZen™ Protection Devices for USB 3.0
TE Connectivity has expanded its PolyZen™ product portfolio with the new ZEN059V130A24LS Zener diode device. This TE Connectivity integrated device offers complete circuit protection for electronics with USB ports and meets USB 3.0 Suspend Mode power-consumption requirements. PolyZen devices are polymer-enhanced Zener diodes that help provide coordinated protection against damage caused by overvoltage, overcurrent, and ESD transients in a single package. The TE Connectivity PolyZen ZEN059V130A24LS combines high power-absorption capabilities with low Vz (Zener voltage) and low power consumption. With a Vz below 6 volts, the device helps protect sensitive downstream electronics, and its low 5V power consumption meets USB 3.0 Suspend Mode requirements. For USB 3.0 devices, the PolyZen ZEN059V130A24LS can be placed on the USB input port, the Powered-B plug, or any supplementary power port. The new device offers designers the simplicity of a high-power clamping diode while obviating the need for significant heat sinking.
