CMSZDA8V2 TR

Diodes are some of the most basic types of semiconductor components available. Zener diodes, in particular, have an interesting ability to maintain a constant voltage within the circuit. By installing Arrays of Zener diodes, the user can further increase the stability and performance of the circuit. In this article, we will look at one such Array of Zener Diodes, the CMSZDA8V2 TR, and discuss its application field and working principle.

Applications

The CMSZDA8V2 TR from Zetex is an Array of transient voltage suppressor (TVS) diodes. It is designed to provide overvoltage protection against surges from static discharge and power anomalies. It is particularly suitable for protecting low cost consumer electronics, such as portable devices and connectors.

The device is rated for very fast transients in the range of 45 nanoseconds and can handle continuous power dissipation of a maximum of 8 watts. It is available in an easy-to-use SOIC package, providing efficient overvoltage protection while also keeping down assembly costs.

Working Principle

The CMSZDA8V2 TR is an Array of 8 Zener diodes, each rated for a breakdown voltage of 8 volts. When the applied voltage exceeds 8 volts, the Zener diode will turn on and conduct current, thus limiting the voltage to 8 volts. Because the CMSZDA8V2 TR can handle surge currents of up to 5 amp peaks, it can provide impressive overvoltage protection.

The device also has a low reverse leakage current of only 15 µA at 8 volts, which makes it easy to use in current-sensitive applications. This feature also contributes to a low operating temperature of the device, allowing it to be used in hot environments where cooling is not an option.

Conclusion

The CMSZDA8V2 TR from Zetex is a convenient and cost-effective Array of Zener diodes, suitable for providing overvoltage protection in various consumer electronics applications. Its fast response time and low reverse leakage current offer dependable protection, while its low operating temperature allows use in a wide range of environments.
