Tyco Electronics’ PolyZen ZEN059V130A24LS device helps provide circuit protection for electronics with USB ports and meets Suspend Mode power-consumption requirements for USB 3.0. The polymer-enhanced Zener diodes help provide coordinated protection against damage caused by overvoltage, overcurrent and ESD transients in a single package. The PolyZen ZEN059V130A24LS device combines high power-absorption capabilities with low Vz (Zener voltage) and low power-consumption. Due to the device's polymer thermal-protection architecture, it is able to absorb high-energy pulses and effectively block overvoltage and reverse bias sources that could ultimately damage a stand-alone Zener diode. With a Vz below 6 V, it helps protect sensitive downstream electronics, and its low 5 V power consumption meets USB 3.0 Suspend Mode requirements.
