Transient voltage suppressors (TVS) are components which help to prevent damage to electronic equipment from transient voltage, such as from electrostatic discharge (ESD) or from the effects of an inductive or capacitive surge. The SM6T22AHE3/5B is a bi-directional TVS diode that is specifically designed for high-speed signal line protection. In this article, we’ll take a look at its application field and working principle.

Application Field

The SM6T22AHE3/5B is specifically designed for use in high-speed signal line protection applications. It has a dedicated high-power discharge circuit, which makes it suitable for use in systems that require a high degree of protection from fast rising transients. It is designed to protect data lines (such as USB and Ethernet), HDMI and DisplayPort connectors, and other high-speed cables from damaging transient voltages. It has a low operating capacitance and a wide operating range, making it ideal for protecting a wide variety of devices.

Working Principle

The SM6T22AHE3/5B is a bi-directional diode, which means that it is capable of protecting both positive and negative voltages. It works by quickly clamping high voltage transients to a level below which the protected device can tolerate. It has a dedicated high-power discharge circuit, which allows it to protect against fast rising transient voltages. This makes it ideal for use in applications such as USB 2.0, HDMI, DisplayPort, and other high-speed data lines. The diode also has a low forward voltage drop, which makes it suitable for use in power supply lines which require a high level of transient protection.

The SM6T22AHE3/5B also has a low operating capacitance. This means that it has low interference with high-frequency signals, making it suitable for use in sensitive data acquisition systems. Lastly, the diode is configured to be soldered down onto a PCB or a printed circuit board. This makes it easy to install and remove as necessary.
