SA6.5C-E3/73

SA6.5C-E3/73 Application Field and Working Principle

The SA6.5C-E3/73 is a type of transient voltage suppressor (TVS) diode. A TVS diode is a type of diode that is designed to protect electrical components from transient or surge voltages. The SA6.5C-E3/73 is a low-clamping transient voltage suppressor that can protect against both static and dynamic transients, and have a low-junction capacitance.

The SA6.5C-E3/73 features excellent clamping capability with a fast response time of less than 1.1ns. It is designed to provide protection from overvoltage in consumer, automotive, and industrial applications. This device has a voltage range of 6.5 volts and is capable of conducting up to 200A of current. It is also capable of handling high-frequency transient voltages in both AC and DC.

The SA6.5C-E3/73 is designed with a cut-off voltage of 6.5 volts, which prevents it from conducting current when the voltage exceeds 6.5 volts. This ensures that the device provides protection from overvoltages. When the voltage exceeds 6.5 volts, the diode begins to conduct, and the current is limited to a maximum of 200A. This allows the SA6.5C-E3/73 to protect sensitive components from damage due to high current.

The working principle of the SA6.5C-E3/73 is based on the Zener diode. It consists of a SiO2 layer with a heavily doped N-type region and a lightly doped P-type region. This sets up a reverse biased structure, which limits the voltage across the device. When the input voltage exceeds 6.5 volts, the reverse bias breakdown and begins to conduct current. The amount of current conducted is limited by the current rating of the device, which is 200A. This prevents damage to the components due to overcurrents.

The SA6.5C-E3/73 is ideal for use in applications such as consumer electronics, automotive, and industrial control equipment. It is capable of providing protection from static and dynamic transients, as well as high-frequency spikes. It is a reliable and efficient device for protection of sensitive components from overvoltages and overcurrents.
