The CZRUR3V0B-HF is a single Zener diode primarily used for voltage regulation. It has a sharp reverse breakdown voltage of 3.0 volts and a power dissipation capability of 500mW. Other features such as a very low forward voltage drop, high stability, and small current leakage make this diode an ideal choice for a wide variety of applications.

Features

• Low forward voltage drop: 0.6 V maximum
• Reverse breakdown voltage: 3.0 V
• Power dissipation: 500 mW
• High stability
• Low thermal resistance
• Low current leakage

Applications

The CZRUR3V0B-HF Zener diode is ideal for a range of voltage regulation applications. It is commonly used as a voltage reference in active filters, voltage regulators, power supply circuits, and other analog circuitry. It is also used for bypassing and clamping, across-the-line surge protection, and transients voltage suppression (TVS) applications.

Working Principle

The CZRUR3V0B-HF Zener diode works by using the avalanche effect when voltage is applied. A silicon PN junction is reverse biased on the diode. The applied voltage is increased until it is higher than the Zener breakdown voltage, at which point it will then conduct current. This is because the electric field at the junction is so strong that it will cause the electrons to accelerate and collide with atoms in the junction, releasing secondary electrons and creating an electric current.

As long as the applied voltage is higher than the Zener breakdown voltage, it will allow current to flow. The Zener diode will then act as a voltage regulator, maintaining the output voltage at a consistent level regardless of changes in the current or temperature.

Conclusion

The CZRUR3V0B-HF single Zener diode is an ideal choice for applications requiring a low forward voltage drop, high stability, and small current leakage, as well as voltage regulation. With a reverse breakdown voltage of 3.0 volts, power dissipation capability of 500mW, and a wide range of applications including active filters, voltage regulators, power supply circuits, bypassing, and clamping, the CZRUR3V0B-HF makes a great choice for many projects.
