Diodes - Zener - Single

The CZRU52C15 is a silicon planar Zener diode manufactured by Cornell Dubilier. It is housed in a hermetically sealed DO-7 package and is used for applications with a single breakdown voltage. These applications require devices with stable and low temperature coefficient characteristics, which the CZRU52C15 provides.

Application Fields

The CZRU52C15 is designed predominately for use as a voltage regulator in low voltage applications, when a constant forward voltage is required to be maintained. These applications include voltage regulation for instrumentation, microwave control and other sensing and control circuits. The device also finds use in shunting and supervising circuits since its reverse voltage is designed to remain within specified limits.

Operating Principle

The CZRU52C15 operates predominantly in a reverse breakdown mode, with a breakdown voltage of 5.2V. In the reverse bias mode and when the voltage exceeds the Zener breakdown voltage, conduction occurs, resulting in linear regulation as current is maintained at levels similar to that in the forward bias mode. The Zener voltage of the CZRU52C15 has a very low temperature coefficient and is extremely stable.

In practice, the operating principle determines the performance and behaviour of the device. The CZRU52C15 is designed to maintain the constant reverse voltage while operating within the predetermined power maximum rating. To ensure the stability this provides over temperature and other environmental factors, the reverse voltage must remain within specified boundaries of the manufacturer.

Package

The CZRU52C15 is housed in a hermetically sealed DO-7 package. The package features an interior glass mount, hermetically sealed and filled with nitrogen to prevent the escape of moisture. The package also features a front-mounted clipping profile, which helps ensure that the device is held in place during installation. Additionally, the CZRU52C15 is RoHS compliant and UL recognized.

Testing

It is essential to ensure the reliability and performance of the CZRU52C15; therefore, the device is subject to rigorous testing by a third-party service provider. This type of testing ensures that the device operates in accordance with its specification, providing the user with confidence in the performance and reliability of the device. Additionally, all of the materials used in the manufacture of the CZRU52C15 comply with international safety and environmental standards.

Conclusion

The CZRU52C15 is a silicon planar Zener diode manufactured by Cornell Dubilier and housed in a hermetically sealed DO-7 package. It is designed for use in applications requiring a single breakdown voltage and is an excellent choice for circuits requiring voltage regulation and shunting in low voltage circuits. The CZRU52C15 is also RoHS compliant and UL recognized and is subject to extensive testing to ensure its reliability and performance under various environmental and operational conditions.
