Zener diode is a special kind of diode that allows current to flow in the forward direction in the same manner as an ideal diode, but also permit it to flow in the reverse direction when the voltage is above a certain value known as the breakdown voltage of Zener diode, Zener knee voltage or Zener voltage. Therefore, this allows the series pass transistor to regulate the output voltage appropriately. Zener Diode VISHAY | 500mW | 10/25/50/100 Stück | Spannung 2,4V - 75V | Dioden. 2 (i),find the maximum and minimum values of zener diode current. Produktart: Zener-Diode.
