Zener Diode Power Rating Calculatior

Access Zener Diode Power Rating Calculator. The power rating of a Zener diode indicates the maximum power that the diode can safely dissipate. Power= voltage x current. If a a zener diode has a zener voltage, VZ of 5.1W, you can use the power rating to find out how much current can flow through the diode by the formula, IZM= PZM/VZ. Enter value and click on calculate. In the formula below, power equals the voltage multiplied by the current. IZM is the maximum current that can flow through the diode, and PZM is the diode’s maximum power dissipation, and VZ is the Zener voltage.
