Circuit Protection Kits - TVS Diodes

Transient voltage suppressors (TVS) are key components for circuit protection, providing protection from high-voltage transients generated by the environment, or from electrostatic discharge (ESD) events. The TVS diodes in the Q3108517 series are designed to protect sensitive electronic circuits from ESD and overvoltage transients.

Overview

The Q3108517 series of TVS diodes is manufactured by a leading supplier of electronic components. They are designed to protect lines and data ports from overvoltage transients. The TVS diodes provide both common-mode (CM) and differential-mode (DM) protection for signals up to 8V. The components are RoHS compliant, and offer reliable protection from ESD events.The TVS diodes are in an SOT-23 package with a low threshold voltage for fast response time. They are designed to dissipate excess power during the transient surge, while offering very low leakage current in normal operation. The TVS diodes are available with various ESD protection levels, such as IEC 61000-4-2 and GOST.

Application fields

The TVS diodes from the Q3108517 series are suitable for a variety of applications, such as industrial and consumer electronics, USB charging circuits, automotive systems, and more.The components are particularly suitable for use in mobile phones, tablets, and other portable devices. The low-profile SOT-23 package combined with the fast response times and low-leakage characteristics makes these components an ideal choice for the protection of high-speed data and power lines.The TVS diodes can also be used in automotive systems. The transient suppression performance of these components enables them to protect sensitive electronic components from voltage transients caused by engine ignition or other events. The ESD protection levels also make these components suitable for use in automotive applications.

Working principle

The working principle of the TVS diodes is based on a Zener diode. Zener diodes are a special type of diode that regulate the current across a PN junction. When the anode voltage reaches a certain threshold (known as the Zener voltage), the Zener diode begins to conduct, and this increases the current through the diode.The TVS diodes employ this principle to provide protection from transient overvoltage. When the voltage exceeds the rated reverse voltage of the diode, the TVS diode will become forward-biased and conduct. This reduces the voltage across the protected circuit, thus providing protection.

Conclusion

The Q3108517 series of TVS diodes are designed to provide reliable ESD and overvoltage protection for sensitive electronics. These components are available in an SOT-23 package, have a low threshold voltage, and offer fast response times for excellent transient suppression. The TVS diodes are suitable for use in a variety of applications, including mobile devices, USB charging circuits, and automotive systems.
