Application Fields

The 3EZ82D/TR12 is used in a variety of electronic applications. It can be used as a voltage clamping device to limit the voltage of signals that pass through it. It\'s commonly used as a power supply regulator in amplifiers, controllers, and other audio and video equipment. It can also be used in telecommunications systems and digital circuits to protect them from voltage spikes.

Working Principle

The 3EZ82D/TR12 is a Zener diode, which makes use of a voltage dependent behavior. It is designed with a Zener junction, which passes the current in the forward direction and blocks it in the reverse direction. By controlling the amount of reverse current, it can also be used as a voltage-stabilizing circuit. When a voltage greater than the breakdown voltage is applied across the diode, the junction will conduct in the reverse direction and reduce the output voltage. This helps to maintain the output voltage at a fixed level in a wide range of input voltages.
