It can be used in power supplies, power regulators and rectifier circuits to provide a range of regulation between its breakdown voltage and peak inverse voltage. It is also used in switching applications where it acts as a reverse breakdown device to protect other components from the effects of overvoltage. In addition, it can also be used in voltage reference circuits, voltage control, low voltage logic and interface circuits.

Working Principle of 1N4745APE3/TR12

The 1N4745APE3/TR12 Zener Diode works on the principle of reverse breakdown of a diode junction. Unlike normal diodes that allow current flow in one direction only, a Zener diode is designed to breakdown at a pre-specified voltage when it is forward biased. When this voltage is exceeded, a Zener diode produces an avalanche breakdown and a large current flows through the device. This causes a voltage drop across the diode, thus providing a regulated output voltage.

When the 1N4745APE3/TR12 Zener Diode is operated in the reverse bias mode, it behaves as a normal diode and conducts current only in one direction. By performing reverse bias, the magnitude of the applied voltage is reduced to below the breakdown voltage. This protects other components from the effects of overvoltage.
