A CDLL3025 is an inline single Zener diode that is primarily used to provide a protected and limited voltage level. It is used in many applications, such as low voltage protection, signal and pulse protection, ESD protection, voltage clamping, and noise suppression.

Applications

The CDLL3025 is ideal for applications such as general purpose low voltage protection, signal and pulse protection, ESD protection, voltage clamping, and noise suppression. It has a wide range of uses in data acquisition, switching power supplies, automotive, industrial, IoT, and communication applications. Additionally, it can be used to provide robust protection against transients, spikes and other voltage source instabilities. The CDLL3025 can also be used as a voltage reference in voltage-controlled electronic circuits.

Working Principle

The CDLL3025 works by using the Zener Effect. This effect occurs in reverse-biased semiconductor junctions when the voltage across the junction exceeds the breakdown voltage, at which point the junction resists an increase in the current through it. In a diode, such as the CDLL3025, this causes a voltage to be developed across the diode equal to the Zener breakdown voltage. This provides a stable, constant reference voltage, regardless of changes in the external circuit.

The CDLL3025 has a Zener breakdown voltage of 30V. When the voltage across the diode exceeds this value, a fixed potential is generated across the diode and the current through it is limited. Thus, it is an ideal choice for low voltage protection, signal and pulse protection, ESD protection, voltage clamping, and noise suppression. It has a very high surge current rating of 40A for 0.5 seconds, making it well suited for high power applications.

Features

The CDLL3025 has a number of advantages over other Zener diodes. It has a low forward voltage drop of 0.5V. It has a higher voltage breakdown of 30V. It is also small in size, measuring just 2.5mm x 1.62mm. It is RoHS compliant, for those applications which require it. The maximum reverse surge rating is 40A for 0.5 seconds, making it well suited for high power applications. Finally, it has a wide working temperature range of -65 C to + 175 C.

The CDLL3025 is an excellent choice for a wide variety of low voltage protection, signal and pulse protection, ESD protection, voltage clamping, and noise suppression. With a wide range of uses in data acquisition, switching power supplies, automotive, industrial, IoT, and communication, the CDLL3025 is a cost efficient and effective way to protect sensitive equipment from voltage transients, spikes and other voltage source instabilities.
