The CLL4751A is a Silicon Epitaxial type Zener diode, which is designed for use in applications where a low leakage current, a low power consumption and a high reliability are desired. It is a single element device with a maximum reverse voltage (VR) of 27 V and a rated power dissipation (PD) of 500 mW.

The CLL4751A Zener diode has a wide range of applications, ranging from voltage regulation to overvoltage protection. As a voltage regulator, it is used to maintain a regulated voltage level across a DC circuit. The Zener diode can be used with a resistor and a capacitor to form a voltage regulator circuit, in which the Zener maintains the regulated voltage and the resistor regulates the power current. The capacitor is used to filter AC noise and provide charge recovery. The CLL4751A can also be used as an overvoltage protection device. When the voltage in the circuit exceeds the Zener breakdown voltage, the diode begins to pass current and provides a low impedance path. This keeps the voltage across the circuit at a safe level.

The CLL4751A Zener diode has a working principle that is based on the Zener breakdown effect. When a reverse bias is applied across the diode, the electric field between the P-type and N-type junctions increases until it reaches a critical value, which causes a \'breakdown\' phenomenon. This breakdown triggers the sudden initiation of a large current flow through the two junctions. The exact breakdown voltage is determined by the doping level of the two junctions and by their spacing. The Zener diode dopants create energy band structures which create and control the Zener breakdown voltage.

The CLL4751A TR Zener diode is also designed to maintain a constant voltage level across a DC circuit. When the voltage across the circuit increases above the Zener breakdown voltage, the diode begins to act as a current regulator, allowing current to flow while maintaining the same voltage across the circuit. This makes the CLL4751A an ideal solution for applications where a constant voltage level is required, such as in voltage regulator circuits. The TCR (temperature coefficient of regulation) of the diode is also low, allowing the Zener diode to maintain an accurate voltage regulation over a wide temperature range.

The CLL4751A offers excellent performance in applications where a low power consumption, a low leakage current, a high reliability and a constant voltage level are desired. The single element device is also designed to provide a low TCR, making it an ideal solution for voltage regulation applications. The Zener diode’s wide range of applications covers voltage regulation and overvoltage protection, making it an invaluable device for a wide range of applications.
