What is the Power Rating, PZM , of a Zener Diode?
The Power Rating, PZM, of a zener diode is the maximum amount of power that a zener diode can safely handle.
If this power rating is exceeded, the zener diode may be damaged or destroyed by the excess power.
A typical power rating of a zener diode is 1 watt, though it can vary depending on the specific zener diode in use.
The power rating of a zener diode is the amount of voltage and current that the diode can handle. 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.
The rating, PZM, has the subscript, Z, standing for zener, and M, standing for Maximum.
