CDLL4928: Application Field and Working Principle

The CDLL4928 is a high power, integrated Zener diode from Diodes Incorporated, targeted for use in applications such as automotive and industrial electronics. By employing their cutting-edge technology, they boast improved performance over their predecessors, with a wide operating temperature range, high switching speed, low power consumption and excellent reliability. So, how does it all work? Let’s take a look.

Field of Application

Unlike regular power diodes, the CDLL4928 is particularly well-suited to automotive and industrial applications. In automobiles, it is used to provide voltage protection against sudden spikes, as well as to protect other components from damage due to an overcurrent or a fault in the system.In industrial applications, the CDLL4928 can be used to protect sensitive electronic components from static electricity and other anomalies. They can also be used in power supply circuits to provide constant, stable voltages for use in industrial machinery.

Working Principle

The CDLL4928 functions similarly to a regular diode, but with one major difference: it is designed to automatically reconfigure itself to ensure that its output voltage does not exceed a certain threshold. This threshold is determined by the "Zener voltage," which is the voltage level at which the diode switches from its normal forward-biased state to its reverse-biased state to limit the output voltage.The CDLL4928 consists of two distinct elements: the body diode and the Zener diode. The body diode acts as a normal diode, conducting current in one direction only and dissipating excess power in the form of heat. The Zener diode then takes over and begins to regulate the voltage when it exceeds the Zener voltage.At this point, the diode is said to be in the "Zener region," where it will remain until the voltage drops back down to the Zener voltage. Once it does, the diode then switches back to its normal forward-biased state, which allows it to conduct current once again.

Conclusion

The CDLL4928 from Diodes Incorporated is a high power, integrated Zener diode designed to provide voltage protection for electronic circuits in automobiles and other industrial applications. With a wide operating temperature range, high switching speed, low power consumption, and excellent reliability, it is ideal for these types of applications. It works by automatically reconfiguring itself to ensure that its output voltage does not exceed the Zener voltage, at which point it switches to its reverse-biased state to limit the output voltage.
