Diodes are essential components used in a wide range of applications including power rectification, voltage clamping, and low-noise generator circuits. Zener diodes, in particular, are widely used for regulating, protecting or generating a stable reference voltage for the circuits to operate. The TLZ22C-GS08 is a single-zener diode which has a wide range of application in the most common and advanced electronic fields.

Applications

The TLZ22C-GS08 offers very low power consumption and high stability over temperature and time. It is designed for high-precision regulation in AC/DC power supplies, as well as voltage stabilizers and other voltage regulation circuits. Additionally, its low capacitance also makes it ideal for automotive power supply applications, such as electronic petrol injection system, ABS systems, and digital control systems. It is also suitable for use in other applications such as voltage spike suppression, current-limiting circuits and in peak-current boosting.

Working Principle

The TLZ22C-GS08 is a voltage-regulator diode. It features a breakdown voltage Vz of 7.8V at a test current of 5mA. In normal operation, the TLZ22C-GS08 operates in its reverse-breakdown region. It functions as a voltage regulator when the forward current is limited to a specified value. This specific current is determined by the zener impedance of the device, which is the ratio between the zener voltage and the test current used for performing the electrical characteristics test. This ratio is called Z ZT and its value for the TLZ22C-GS08 diode is 8.

When the TLZ22C-GS08 is connected to a resistive load, the current will flow from the load to the cathode side of the diode and the zener voltage will be regulated. This regulation process occurs when the voltage across the resistor reaches the zener voltage. At this point, the control current will flow through the resistor, limiting the voltage across. This mechanism is the basic principle of Zener diode voltage regulation.

Conclusion

The TLZ22C-GS08 is a single-zener diode which is suitable for various applications including power supply, voltage stabilizers, voltage spike suppression, and current-limiting circuits. The device features a reverse breakdown voltage of 7.8V at a test current of 5mA, offering high stability and low power consumption. Its working principle lies in the control current flowing through the resistor, limiting the voltage across the zener diode.
