TVS (Transient Voltage Suppression) diodes offer a reliable layer of protection for electronics and electrical systems against high amplitude transient voltages. The USB50824/TR7 is a transient voltage suppression diode designed to protect high speed data lines from electrostatic discharge (ESD) and other transients. This diode is ideal for automotive, industrial, and consumer applications.

Application Field

The USB50824/TR7 is designed to protect data lines in consumer, automotive, and industrial applications from ESD and other transients. It is an ideal solution for data line applications in automotive infotainment systems, portable electronic devices, industrial control systems, and consumer electronic devices. Its low capacitance makes it ideal for high speed data lines in Automotive Ethernet systems.

Working Principle

The USB50824/TR7 is a low capacitance bidirectional TVS diode. It features a symmetrical Clamp structure which provide low capacitance of 2.3 pF, allowing fast response times to protect against the most hazardous transients. The low capacitance prevents signal distortion on high speed data lines, ensuring maximum throughput.

When a transient voltage exceeds the diode\'s breakdown voltage, the diode becomes conducting, providing a low impedance path to ground. The current is then limited due to the diode\'s low ESD limit, and the transient is clamped. When the transient voltage returns to within normal operating levels, the diode reverts back to its non-conducting state.

The USB50824/TR7 is available in an SOT-23 package, providing low cost and efficient protection for mobile devices. It has an operating voltage of 5.0 VDC and an ESD protection rating of 20 kV for Human Body Model (ESD HBM) and 16 kV for Machine Model (ESD MM). It is able to dissipate up to 10 Watts of power without sustaining damage.

Conclusion

The USB50824/TR7 is a low capacitance bidirectional TVS diode designed to protect high speed data lines from electrostatic discharge (ESD) and other transients. It has a symmetrical Clamp structure which provides a low capacitance of 2.3 pF for fast response times, and is available in an SOT-23 package. The USB50824/TR7 is well suited for automotive infotainment systems, portable electronic devices, industrial control systems, and consumer electronic devices.
