SMDA05C-8E3/TR7 TVS - Diodes Application Field and Working Principle

The SMDA05C-8E3/TR7 is a type of transient voltage suppressor (TVS) diode designed to protect sensitive electronics from electric voltage transient surges. It is a unidirectional, non-transparent, bidirectional diode available in axial-leaded and surface mount packages. It has low resistance and low capacitance design, with peak surge- currently of 5A and clamping voltage of 8.3V. The SMDA05C-8E3/TR7 TVS diode can be used in a variety of application fields, such as consumer electronics, automotive, lighting, communication networks, industrial equipment, and medical equipment.

Working Principle of TVS diode

The TVS diode can be thought of as a one-way valve that allows current to flow in only one direction. When a voltage transient occurs, the voltage increases above the rated voltage and the diode turns on, preventing current through the device from exceeding its rated current. When the voltage transient subsides, the diode turns off and the current flow returns to its normal level. It is important to understand the working principle of TVS diodes to obtain the maximum protection and performance.
