CLL5229B TR Application Field and Working Principle

The CLL5229B TR is a single Zener diode designed to stabilize electrical circuits. In particular, it is mainly used to limit the voltage provided to the circuit and reduce the risk of electrical damage and lower the power consumption in order to reduce costs. It is also often used to create a reference voltage.

The CLL5229B TR is composed of a single N-type layer of silicon sandwiched between two P regions. This is known as a p-n-p junction. The P-region consists of a high-resistance semiconductor material doped with antimony, while the N-region is a low-resistance semiconductor material doped with arsenic. A heavily doped N+ region partially overlaps the N-region and acts as a Zener breakdown region across which a reverse biased voltage can be applied.

When the reverse biased voltage is less than the Zener breakdown voltage, a small current flows in the circuit, but as the reverse bias increases, the Zener breakdown voltage is passed and the current begins to rise exponentially. This is known as the Zener breakdown, and the diode is said to be ‘on’. In this state, the diode has a low impedance, thus allowing a significant amount of current to flow through it. This current can be used to limit the provided voltage and stabilize the operation of the circuit.

The CLL5229B TR is most often used in audio equipment, particularly in the stabilizing of pre-amplifiers and microphone pre-amps. It also finds use in various power supply designs, where it can prevent voltage spikes from damaging the circuit and ensure the system functions properly. In addition, it is commonly used in voltage regulation and clamping applications, such as in power transistors, SCR and triac circuits.

The CLL5229B TR has a maximum reverse voltage of 25V and a breakdown voltage of 5.6V. It has a maximum power dissipation rating of 500mW, and can withstand repetitive peak reverse voltages of up to 37.5V. The device can operate at temperatures ranging from -55°C to +150°C.

Overall, the CLL5229B TR is a robust single Zener diode designed to stabilize electrical circuits and limit the voltage provided to them. It has a wide range of applications, ranging from audio equipment to power supplies, and can be used to reduce the risk of damage and lower power consumption. The CLL5229B TR is a reliable choice when it comes to voltage regulation and clamping.
