Screen-printed thick film varistors (TFV) based on ZnO powder were developed with the aim to protect IGBT power transistors against overvoltages. The electrical characteristic of TFV was shown to depend on the electrode composition. Furthermore, characterization of the microassembly [electrodes/ZnO/Al2O3 substrate] proved that in the case of ZnO layers fired at 1200 °C, ...Read less <
