High-voltage Zener diodes can be used as overvoltage protection diodes for Integrated
Circuits (IC) due to their ability to cut off the applied voltage at a well-defined value. One
important application is the protection of EL driver circuits where a driver IC is connected
to an EL foil. Since both the foil as well as the IC are sensitive against voltage overstress,
it is necessary to install an additional protection device in the circuit. Commonly, a
peak-to-peak voltage of 220 V should not be exceeded, such that two 100 V diodes in
back-to-back configuration are used.
