TVS-diodes are special devices designed to protect electronic components from voltage transients. The SA6.5-E3/73 is an example of a TVS-diode and is designed to protect a variety of electronic components in a wide range of applications. This article will discuss the application field and working principle of the SA6.5-E3/73.

The SA6.5-E3/73 was specifically designed to provide effective protection for low-voltage equipment against transient and static surge discharge. The TVS-diode is also commonly used to protect sensitive equipment from high voltage transients, such as those caused by lightning and other electromagnetic interference (EMI).

It is a single-mode device that offers high-capacity overvoltage protection, fast response time, and low capacitance. It is also designed to minimize the transient-induced voltage drop, thus reducing the risk of equipment failure due to voltage transients. The SA6.5-E3/73 is ideal for use in a wide range of applications, such as in the automotive and telecom industries, or for any other application where transient protection is of the utmost importance.

The working principle of the SA6.5-E3/73 is based on the diode’s ability to clamp the voltage, i.e., it reduces the voltage in case of an overvoltage, till it reaches a predetermined level, which is typically low enough to protect sensitive equipment or components from damage. This is achieved by the diode\'s PN-junction, which acts as a one-way barrier that prevents the current to flow directly through the device, but rather conducts the current around it, thus redirecting the current away from the component. This method of protection is effective against most high-voltage transients.

The SA6.5-E3/73 is constructed from two diodes, a pair of insulated gates, and two complementary type field effect transistors (FETs). The two diodes cooperate to block unwanted voltages, while the two insulated gates enable changes in the threshold voltage levels. The FETs protect against static and transient surges. The working principle of the device is such that when a high voltage transient incurs, the insulated gates open and the two diodes start to conduct, thereby dissipating the transient. The FETs then block any voltage dealing with the upper side of the device, while the lower side device is still conducting and dissipating the transient.

In conclusion, the SA6.5-E3/73 is an effective TVS-diode designed to protect electronic components from transient and static surge discharge, as well as other high-voltage transients. It can be used in a variety of applications, such as those in the automotive and telecom industries. The device’s working principle is based on the diode’s ability to clamp the voltage, and the two diodes, two insulated gates and two FETs of the device cooperate to provide protection against static and transient surges.
