CZRER52C11 Discrete Semiconductor Products

The CZRER52C11 is a member of the CZER series of single Zener diodes, made with 125 V, 11 V reverse voltage rating and 500 mW peak surge power dissipation. The device is predominantly used for general purpose voltage and over-voltage limiting applications. For instance, CZER52C11s are commonly found in voltage clamping systems, voltage reference systems, reverse-bias protection circuits, and power governing systems. As a Zener diode, the CZER52C11 has a simple but effective working principle.

Applications of the CZER52C11

The CZER52C11 is primarily used for voltage and over-voltage limiting within a wide range of systems. Within voltage clamping systems, the CZER52C11 diode provides surge protection against damaging power transients. For references systems, the device is used to provide an accurate reference voltage across applications. The CZER52C11 may also be employed as a reverse-bias protection circuit, or used in power governing systems to regulate current flow and maintain a safe level between components.

How it Works

The CZER52C11 Zener diode works by exploiting the phenomenon of reverse-bias breakdown. When reverse-biased, the Zener diode will conduct a predetermined current, determined by the applied voltage and will remain in that state until the voltage exceeds the diode’s breakdown voltage, at which point the diode will cease to conduct. The breakdown voltage is determined by the width of the band gap in the material the diode is made from.

The wide band gap of the CZER52C11 creates a higher breakdown voltage, making it better suited to applications such as over-voltage protection and voltage regulation. The breakdown voltage is also temperature-dependent, so temperature-based compensation circuits may be used to ensure that the breakdown voltage stays constant over a given temperature.

Advantages of the CZER52C11

The CZER52C11 diode offers a range of advantages over alternative solutions. Firstly, due to its wide band gap, the CZER52C11 diode is able to handle higher breakdown voltages, making it better suited for HI/LO voltage protection applications. In addition, the CZER52C11 is relatively inexpensive, and has a high tolerance to heat, making it suitable for thermal applications.

Furthermore, the CZER52C11 has a low capacitance, making it suitable for high frequency applications, and due to its low power consumption, the diode is well suited to low-power applications, such as battery-powered systems. Finally, the diode is also resistant to electrostatic discharge, making it suitable for sensitive systems.

Conclusion

The CZER52C11 is a single Zener diode primarily used for the purpose of general-purpose over-voltage limiting and voltage regulation applications. It is a cost effective solution that offers a range of advantages such as high breakdown voltage, high tolerance to heat, low power consumption, low capacitance, and electrostatic discharge protection.
