Diodes are semiconductors that permit the flow of electrical current in one direction while in the opposite direction it is almost completely blocked. Zener diodes, single or double, are specially manufactured and designed to operate in the reverse biased breakdown mode.

The CDLL5240B is a single Zener diode designed for voltage regulation applications. The CDLL5240B diode operates as a voltage regulator and is commonly used in applications such as: Cell phone VCO, Hi-fi speaker systems, and other general protection against over-voltage. The CDLL5240B features a low profile, wide dynamic range, and a 400 mA maximum current capability.

The working principle of the CDLL5240B begins with an N-channel MOSFET. When the voltage is below the breakdown voltage, the MOSFET is off and the current is limited by the internal series resistor. When the voltage exceeds the breakdown voltage, the MOSFET turns on, allowing the current to flow freely through the diode. This action regulates the voltage, providing a constant output.

The actual breakdown voltage of the CDLL5240B is determined by several key factors. The resistance of the internal series resistor is the primary factor and must be chosen based on the output voltage and current requirements. The ambient temperature also plays a role in determining the breakdown voltage. The temperature coefficient of the diode is typically around −2 mV/° C.

The CDLL5240B is a low-leakage Zener diode with a maximum leakage current of 5 µA. This makes it suitable for use in high-precision applications such as voltage regulation for cell phones and hi-fi audio systems. The CDLL5240B is also designed with a robust package structure and Electrostatic Discharge Protection of up to 500V.

The CDLL5240B is designed to operate over a wide range of temperatures and supply voltages. It can withstand up to −65 °C and as high as + 125 °C. The breakdown voltage range is -2V to 40V. The CDLL5240B also provides excellent ESD protection and a wide operating range.

The CDLL5240B is an ideal choice for applications requiring a reliable, low leakage and high current Zener diode. This diode is well suited for voltage regulation, EMI suppression, and line protection in a variety of applications. The CDLL5240B is an excellent choice for use both in commercial and industrial applications.
