The CDLL975A diode is a double-diffused silicon transistor that is designed to function as a medium-power Zener diode and a source of temperature-stable low-voltage reference. It is one of the most popular diodes available and is used in a variety of applications due to its low-voltage and temperature characteristics.

Application Field

The CDLL975A is particularly useful in applications that require low voltage precision, such as power supplies, telecom systems and other low-voltage applications. It also has excellent temperature characteristics and can provide a stable supply of low voltage even in harsh temperatures. It is commonly used as a voltage regulator to stabilize the voltage in a power supply. It can also be used to protect sensitive electronic components from voltage surges. Another common application is in motor control circuits, where it regulates the motor speed by controlling the power to the motor.

Working Principle

The CDLL975A works on a principle of forward-biased current flow. When the diode is forward-biased, current will flow through the junction and generate a voltage across it. The voltage generated across the diode is proportional to the current and temperature. This voltage is known as the Zener voltage and is typically very stable, making it ideal for many applications.

The CDLL975A also has a very good temperature coefficient, which is the rate at which its voltage changes with temperature changes. This makes it ideal for temperature-sensitive circuits, such as power supplies, where it can maintain the output voltage of a power supply even as the temperature changes.

The CDLL975A has a very low “on” resistance (R_d), which means that it will have a very low voltage drop across it when current is flowing through it. This low voltage drop makes it an effective voltage regulator for low-voltage applications.

The CDLL975A also has an internal thermal-protective element that will automatically shut off the diode when the temperature is too high. This feature helps protect sensitive circuitry and can be especially helpful in high temperature environments.
