Application Field and Working Principle

The 1N5343/TR12 device is widely used in audio/video and test and measurement applications. This device provides a stable voltage output in the presence of a varying current input. It remains in a state of constant conduction at the desired voltage output. The applied voltage must exceed the clamp voltage or the breakpoint voltage in order for the device to work. The device maintains the breakdown voltage through negative feedback and remains in a state of reverse conduction until it reaches a cutoff current.

In audio/video applications, a constant voltage level is required for different types of circuits. With the help of the 1N5343/TR12 device, a constant current level is maintained, even when the input current decreases or increases. This helps in maintaining a constant level of audio/video. The 1N5343/TR12 zener diode is also used in many test and measurement applications in order to maintain a constant voltage level.
