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 ...
The circuit diagram shows the over voltage protection as a feature of LM317 linear voltage regulator. The circuit diagram shows the over voltage protection as a feature of LM317 linear voltage ...
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 ...
Toshiba is expanding its surge protection Zener diodes lineup with the addition of four new products to its CUZ series. The CUZ56V, CUZ62V, CUZ68V, and CUZ75V, with Zener voltages (VZ) of 56V, 62V, ...
Varistors, also called metal-oxide varistors (MOVs), are used to protect sensitive circuits from a variety of overvoltage conditions. Essentially, these voltage-dependent, nonlinear devices have ...
