CDLL5229

Diodes - Zener - Single

The CDLL5229 is a Zener diode single which belongs to the category of diodes. It is a two layer diode with symmetrical P/N junctions allowing a low forward voltage drop with low power loss. The CDLL5229 also provides a low leakage current and is typically used as a voltage regulator or surge protector.

The CDLL5229 is available in a DO-41 package. It has a maximum total power dissipation of 1 W and a maximum of 1.5 A. It features a low temperature coefficient and an extended operating range, suitable for both low and high temperature applications.

Application Field

The CDLL5229 is suitable for a variety of applications. Its broad operating range and stability make it suitable for higher temperature applications such as automotive, industrial and aerospace markets. It is also suitable for consumer applications such as personal computers, office equipment, DVD players and home appliances.

The CDLL5229 can also be used in a number of other applications such as voltage regulation in power supplies, surge protection, voltage regulation in mobile phone chargers, protection against electrostatic discharge, protection against lightning strikes and protection against high voltage transients.

Working Principle

The Zener diode single works on the principle that when a diode is reverse-biased, a small reverse current will start flowing. This current is known as Zener current. When the voltage is increased above a specific breakdown voltage known as the Zener voltage or knee voltage, the current starts increasing dramatically. This increase in current is known as the Zener breakdown.

The CDLL5229 has a Zener voltage capability of 5.2 V. This means that when the current through the diode reaches 5.2 V, it will break down and start conducting current which will then be regulated to this voltage level. The Zener diode acts as a voltage regulator which helps to ensure that the voltage does not exceed the specified breakdown voltage.

The Zener diode single also provides protection against high voltage transients. As the current passes through the diode, it is blocked with a reverse bias voltage. This helps to protect the circuits from surges caused by electrostatic discharges and lightning strikes.

In addition, the CDLL5229 is capable of providing low impedance protection. This helps to reduce the losses due to voltage droop and can also reduce EMI interference in sensitive applications.

Conclusion

The CDLL5229 is a Zener diode single which is suitable for a variety of applications such as automotive, industrial and consumer electronics. It is capable of providing a low forward voltage drop with a low power loss, low leakage current and a low temperature coefficient. It provides protection against high voltage transients and is capable of providing low impedance protection.
