CDLL969A

The CDLL969A Zener diode is a single diode that is designed to maintain a stable voltage drop in the reverse-bias circuit, usually around 5 volts. It is often used in voltage regulation and as an over-voltage protection device.

The CDLL969A is a 1N4148 diode with an integrated zinc oxide Zener diode. It has an operating voltage of 4.7 to 5.2 volts, a maximum power of 63 milliwatts, and a maximum reverse voltage of 25 volts. It also has a low forward voltage drop of 0.644 volts at its minimum operating current, which is 100 μA. It has a total device capacitance of 0.8 pF.

The primary purpose of the CDLL969A Zener diode is to provide a stable reference voltage in a reverse-bias circuit. That is, the voltage applied to the diode when the circuit is energized, and the voltage dropped across the diode as current flows, will be relatively constant, usually around 5 volts. This is often used in voltage regulation, so that the load on the circuit remains more or less constant, no matter what the input voltage is.

The CDLL969A Zener diode can also be used as an over-voltage protection device. If the reverse voltage of the circuit exceeds the Zener voltage of this diode, the Zener diode will break down and draw enough current to limit the voltage drop to the Zener voltage. This will keep the load connected to the circuit from being damaged by excessive voltage.

The CDLL969A Zener diode is an inexpensive and reliable device for voltage regulation and over-voltage protection. It is easy to install and provides a stable 5-volt reference for a variety of applications.
