Working Principle

A Zener diode is a reversible semiconductor device which is used to maintain a constant voltage. The diode works in reverse bias mode, allowing an excess current to flow through it while there is not enough voltage to break down into conduction.

In normal operation, the Zener diode allows current to flow through it in both directions. When the forward voltage is greater than the breakdown voltage (VZ), the Zener diode acts as a short circuit and current flows through it as in a regular diode. However, when the reverse voltage is larger than VZ, the Zener diode acts as an open circuit and blocks current from flowing.

When the voltage reaches the breakdown voltage, VZ the current starts to increase exponentially and the diode begins to conduct. This is because the electric field strength increases with an increase in the applied reverse voltage, causing an avalanche breakdown of the p-n junction.

The Zener diode has two primary purposes: voltage regulation and voltage clamping. In voltage regulation, a Zener diode is placed in series with a load to regulate the output voltage. In voltage clamping, a Zener diode is placed in parallel with a capacitor to limit the voltage in peak-to-peak transients.

The DDZ9715-7 Zener diode is an excellent choice for a wide variety of applications requiring stability and reliability. This particular Zener diode offers exceptional performance, making it an ideal choice for a wide range of applications.
