CDLL3039A

The CDLL3039A is a single Zener diode manufactured by Central Semiconductor. It is housed in the 1.3-millimeter, low profile, industry standard SOD-123 package, and is designed for use in applications including high-speed switching and power over Ethernet. This article looks at the CDLL3039A application field and working principle.

Application Field

The CDLL3039A is commonly used in high frequency switching and power over Ethernet applications. It is designed to operate in medium and high frequency switching circuits. It can also be used in power over Ethernet applications, providing protection from power surges and voltage transients, as well as regulating voltage in applications such as POTS telephone and cable modems. The CDLL3039A is capable of operating at frequencies up to 3GHz and provides excellent power supply noise immunity.

The CDLL3039A is a rugged device and is able to withstand high temperatures and maximum power dissipation without degrading performance or reliability. Its low thermal resistance makes it ideal for use in high temperature, high power applications. The CDLL3039A is RoHS compliant and Lead-Free compatible.

Working Principle

The CDLL3039A is a Zener diode which, like a regular diode, operates by allowing current to flow in only one direction. Unlike a regular diode, however, it also operates in the reverse direction, allowing a regulated voltage to be developed across the device when bias power is applied. This voltage is determined by the device\'s breakdown voltage, which can be adjusted to meet the specific requirements of a given application.

The CDLL3039A is a low- leakage, low current Zener diode, designed for high-speed switching applications. It has a maximum operating voltage of 50 V, a maximum junction temperature of 125 °C, and a maximum power dissipation of 500 mW. It has a low junction capacitance of 2.0 pF and a breakdown voltage range of 5.5 to 20V.

When bias power is applied, the CDLL3039A releases a controlled amount of current, which is determined by its breakdown voltage. This helps to regulate the voltage in high frequency applications and protect against power surges and voltage transients. The CDLL3039A has a low clamping voltage, which helps to reduce power loss during high-speed switching operations.

Conclusion

The CDLL3039A is a single Zener diode designed for use in high frequency switching and power over Ethernet applications. It operates by allowing current to flow in only one direction and providing a regulated output when bias power is applied. It is rugged and reliable, capable of withstanding high temperature operation and maximum power dissipation. The CDLL3039A is Lead-Free and RoHS compliant.
