TZX9V1B-TAP

The TZX9V1B-TAP is a diode-type Zener single-element device designed to regulate the output of a power supply. It consists of an anode, a cathode and a pair of very thin and low-resistance reverse-biased P-type and N-type gallium arsenide (GaAs) layers. The thin layers of gallium arsenide give it excellent temperature-compensated voltage regulation. The device also has a high breakdown voltage rating of 9V and a low, temperature-dependent “on” resistance.

Mechanism of Operation

The operation of the TZX9V1B-TAP is based on the basic principle of electrical breakdown. When the anode and cathode of the device are connected in a circuit, electrons are attracted to the anode due to its negative charge. When the voltage between the anode and cathode exceeds the rated voltage of the device, an electrical breakdown occurs. This breakdown causes electrons to ionize and move through the thin layers of gaas, forming an electrical path between the anode and cathode. As current flows through the device, the voltage between the anode and cathode begins to drop. This effect is known as “Munro effect”. The voltage drop is proportional to the current that is flowing through the device. As the voltage drop continues, the voltage between the anode and cathode reaches a steady state, known as the Zener voltage.

Applications

The TZX9V1B-TAP diode-type Zener single-element device is primarily used to control the output voltage of power supplies. It is also used to regulate the line voltage of telephone lines, medical equipment, and other electronic instruments. The device has a high breakdown voltage rating of 9V and a low, temperature-dependent “on” resistance, making it ideal for controlling the output voltage in linear and switching regulator circuits.The TZX9V1B-TAP is also commonly used for circuit protection, particularly for portable devices. When the voltage across the device exceeds the rated voltage, the device will break down and divert the current to the external circuit, preventing the device from becoming damaged. The device is also capable of handling large amounts of transient over-voltage and current, making it useful for protecting power supplies from short-circuits and line spikes.

Conclusion

The TZX9V1B-TAP is a versatile and reliable diode-type Zener single-element device that can be used for a variety of applications. It is ideal for controlling the output voltage of power supplies, regulating telephone lines, and protecting portable devices from over-voltage and current surges. The device has a high breakdown voltage rating and a low thermal-dependent “on” resistance, making it excellent for a variety of circuit protection applications.
