The device can also be used to provide surge protection for power lines, telecom lines, and sensors.

Working Principle

TVS diodes are voltage-dependent components that operate on the principle of capacitive coupling. When the voltage across the diode exceeds its breakdown voltage, electrons are trapped between the junctions of the diode, forming a depletion layer of capacitance which absorbs the excess energy. This process is known as capacitive breakdown, and the resulting current is known as the clamping current. As a result, the TV50C480J-G is able to provide protection from electrical transients while maintaining a low operating voltage.
