WebApr 4, 2024 · As input voltage exceeds Zener voltage, therefore, Zener diode starts working in the breakdown region and supplies 12-volt output voltage. However, the value of Zener current or the current passing through series resistance is determined as follows. I= Vin– Vz/Rs= 30V-12 V/1.8KΩ= 10mA. WebThe Zener diode maintains a constant output voltage in the breakdown region, even though the current through it varies. This is an important feature of the zener diode, which can be used in voltage regulator applications. Therefore a zener diode is sometimes called a Voltage-regulator diode.
WebMar 6, 2024 · If V is the breakdown voltage of the zener diode, the voltage across the load ranges from 0 to V. It doesn't exceed V. Suppose an LED gets damaged beyond 2 V. You could probably use a 1.5V zener across it so that you can protect the LED – Vamsi Krishna Mar 6, 2024 at 9:53 WebAll diodes exhibit rectification when driven in forward bias, and they exhibit a breakdown behavior when driven at high voltage in reverse bias.
