A Zener diode can be used as an overvoltage protector that shunts fault current through ground via a current-limiting resistor (Figure 2). Note that the Zener protection is effective only if the Zener ...

This application note presents the functions of PolyZen devices for the EOS protection in LED applications. It is stated in this article that the PolyZen devices can help in lowering EOS energy levels ...

Although microcontrollers generally run at low voltages, such as 3.3 V, they often need to control loads running at higher voltages like 12 V. If switching the low side isn’t an option, the ...

This overvoltage detector can be connected to any dc power source (Fig. 1). Its purpose is to provide a visual indication of when the voltage exceeds a preset value, which may range from around 3 V ...
