CDLL4474

Application Field

CDLL4474 is a single zener diode from Diodes Incorporated. It is packaged in a SOIC-5 surface mount package, and its dimensions are 3.9mm x 4.9mm. It has wide range of operating temperature, from -65°C to 175°C, making it suitable for all kinds of extreme temperature applications. The diode has a peak power of 1 watt when operating at a temperature of 25°C to 125°C.

This diode can be used in a variety of applications, including voltage regulation, power conditioning, overvoltage protection, and noise suppression. It can be used in electronic circuits to protect against transient overvoltages, protect against power supply noise, or provide a constant voltage output. It can also be used to provide a stable voltage supply for sensitive chips.

Working Principle

The working principle of the CDLL4474 is based on the zener effect. A zener diode is a type of diode that, when operated in reverse bias, breaks down at a pre-defined voltage known as the zener voltage. As the applied voltage exceeds the zener voltage, a small amount of current starts to flow, thereby providing a useful output voltage. The amount of current that starts to flow is determined by the zener breakdown voltage, which allows for precise control over the output voltage.

The CDLL4474 Zener Diode has a breakdown voltage of 4.7V, which allows it to serve as an overvoltage protection device. When the input voltage exceeds 4.7V, a small amount of current will start to flow, thereby limiting the voltage at the output pin. This in turn prevents the overvoltage from damaging any sensitive components in the circuit.

In addition, the CDLL4474 is capable of handling large amounts of current due to its low dynamic resistance. This makes it a good choice for applications that require a large amount of current handling capability, such as power distribution networks and motor control systems.
