The TVS – Diodes are most commonly used for lightning and surge protection. The USB50424E3/TR7 is one of the type of TVS – Diodes used for protection against transient voltage pulses. It is a bidirectional Transient Voltage Suppressor (TVS) designed to protect sensitive electronic devices from voltage transients induced on the data and power supply lines.

The USB50424E3/TR7 is an integrated diode specially designed to protect dataport applications against electrostatic discharges(ESD) of ±25KV air-gap and ±30KV contact discharge, and transient voltage events, which may exceed the absolute maximum voltage ratings of the sensitive equipment. It also withstands the reverse Standoff Voltage of 60 V and peak pulse current of 120A.

It is suitable for use in a variety of applications such as USB3.0, USB2.0, RJ45, and LVDS systems. This device features a very high capacitive discharge protection and, with its fast response time, is suitable for use at the high speed applications where board size and efficiency are essential.

The USB50424E3/TR7 can be used as power line protection for multiple application fields, such as automotive area networks, communication networks, and consumer electronic devices. For automotive applications, it helps protect on-board microprocessors, drivers, and sensors from excessive transients, and helps ensure a higher level of reliability.

The USB50424E3 /TR7 uses silicon avalanche diodes as its main component. A silicon avalanche diode is a type of diode which is capable of withstanding high electric fields. This allows the USB50424E3/TR7 to withstand very large transient voltages without being damaged, making it suitable for use as a TVS-Diode.

When the USB50424E3/TR7 is used as a transient voltage suppression device, it acts as the voltage bridge between the two different voltage levels: the incoming voltage (the transient voltage) and the protected circuit’s voltage (the voltage in which circuitry is designed). This helps protect the sensitive electronic devices and components against any unexpected voltage pulse.

In summary, the USB50424E3/TR7 can be classified as TVS-Diode which is suitable for use in a wide range of application fields, including automotive area networks, communication networks, and consumer electronic devices. Its feature of fast response time makes it ideal for high speed applications where board size and efficiency are essential.
