Working Principle:

The 3EZ11D5/TR12 is a single Zener diode, meaning that it has a single semiconductor junction that exhibits Zener characteristics. This diode works based on Zener effect, which is an electrical breakdown mechanism that occurs in a reverse bias P-N junction. When the P-N junction is reverse biased, an electric field is created which results in a high electric field strength near the junction. This high electric field causes electrons and holes in the depletion region to recombine, leading to a decrease in the depletion region width and an increase in the electric field, which can cause electrical breakdown. When this occurs, current flows through the diode in the opposite direction.

The Zener diode takes advantage of this effect in order to regulate a circuit’s voltage. Basically, when the voltage across the diode rises above a certain threshold, the diode conducts current in the reverse direction, allowing current to flow through it and protect the circuit from any further overvoltage.

The 3EZ11D5/TR12 is designed for use in various electronics applications and its working principle enables it to offer reliable voltage regulation and protection in all types of circuits, making it an ideal choice for general-purpose Zener diode applications.
