The TZX22C-TR is a single Zener diode with a maximum working voltage of 20 volts. It is manufactured by Tzu Technology Co., Ltd. that specializes in semiconductor components. The diode is designed to provide a low-voltage power source for various electronics applications. It is made with a Zener reverse breakdown voltage that ensures stability and reliable performance.

The TZX22C-TR is primarily used to protect circuits from transient over-voltage spikes caused by electrostatic discharges, excessive vibration, or power surges. It works be clamping the voltage to a safe level after a certain voltage is exceeded. Due to its low voltage rating, it is well-suited for use in audio systems, communication devices, and battery-operated products.

This diode features Zhonndimax™ doping technology and precision breakdown voltage, which enable the diode to provide accurate protection and improved junction stability. It comes in a DO-35 package with a maximum power dissipation of 500 mW at an ambient temperature of 25 °C.The package is very compact, measuring 2.4 mm x 1.3 mm in size, making it suitable for limited space applications.

The TZX22C-TR\'s working principle is based on the concept of reverse breakdown voltage of the junction diode. As the magnitude of the applied reverse voltage increases, the current flow through the junction increases. When the applied voltage exceeds the junction breakdown voltage, an avalanche effect occurs, allowing the current through the diode to rise quickly and sharply. This creates a characteristic knee or step in the current-voltage (IV) curve and the voltage after this step forms the Zener voltage, which remains relatively constant regardless of further increases in the applied voltage.

The TZX22C-TR is a good choice for designers looking for an economical Zener diode that can provide reliable voltage clamping protection. It is ideal for use in a variety of applications, such as voltage regulation, alternating current protection, power supply line protection, audio system protection, and other general-purpose applications requiring low reverse breakdown voltage protection.
