The PZU24B3,115 Zener diode is a single, 2–3 watt, voltage regulator and ESD protection device. It is a two terminal, power semiconductor device that can regulate the voltage across it using the breakdown voltage. This is the most common application of Zener diode and is widely used to directly provide a stable voltage. In addition to voltage regulation, the PZU24B3,115 Zener diode is also used for overvoltage protection, voltage clamping, and noise filtering. This article provides a review of the device\'s applications and working principles.

Applications

The PZU24B3,115 is used for a variety of applications, including voltage regulation, overvoltage protection, voltage clamping, and noise filtering. It can be used to create a voltage regulating circuit, such as a voltage regulator. The Zener diode can be connected in parallel with a resistor to form a voltage regulating circuit, which will maintain a constant output voltage. This is widely used in power supplies, battery chargers, and other electronic devices. It can also be used to protect circuits from overvoltage by limiting the voltage that reaches the circuit. In this application, the Zener diode is connected in series with a resistor and can effectively reduce the voltage. In addition, the diode can be used to reduce unwanted noise and clipping voltages in circuits. The Zener diode can clamp the voltage to a pre-determined level and reduce any further fluctuations. Lastly, it can also be used to reduce RF interference in RF applications.

Working Principle

The PZU24B3,115 is a breakdown type Zener diode. It works on the principle of Zener breakdown. Zener breakdown is a phenomenon that occurs when voltage is applied to a diode in reverse bias. When a voltage greater than the Zener breakdown voltage is applied across the diode, the electric field in its depletion region becomes so strong that the electrons and holes become free and move across the junction, creating a conducting path. This breakdown voltage is known as the Zener voltage and can be varied from a few volts to several hundred volts depending on the device.

In the application of voltage regulation, the Zener diode is connected in parallel with a resistor across the voltage source. The diode is reverse biased and its breakdown voltage is selected such that the output voltage is maintained at a constant level. When the output voltage goes above the Zener breakdown voltage, the Zener diode conducts and the output voltage is clamped to the Zener voltage. This keeps the output voltage at the desired level and prevents it from going any higher.

Conclusion

The PZU24B3,115 is a single, 2–3 watt, voltage regulator and ESD protection device. It is widely used for voltage regulation, overvoltage protection, voltage clamping, and noise filtering. It works on the principle of Zener breakdown, in which a voltage greater than the Zener breakdown voltage is applied across the diode and the electric field in its depletion region becomes so strong that the electrons and holes become separated and a conducting path is created. The Zener diode is then used to maintain the output voltage at the pre-determined level and limit any further fluctuations.
