VE07P00231K Circuit Protection

TVS (transient voltage suppressor) diodes are designed to protect sensitive electronic circuits from voltage transients caused by electrostatic discharge (ESD), inductive load switching, and other momentary voltage disturbances. The VE07P00231K TVS diode is a unidirectional transient voltage suppressor that is particularly suitable for various electronics equipment, such as computers, digital cameras, and mobile phones. This article will discuss the application fields and working principles of the VE07P00231K.

Application Field

VE07P00231K TVSs are designed for overvoltage and overcurrent protection in automotive, communication, and other consumer electronic systems, such as computers, digital cameras, and mobile phones. The VE07P00231K is a bidirectional diode which offers protection against transient voltage events. Its low capacitance ensures faster action in the event of a transient overload or fast rise lightning strike.

The VE07P00231K is also designed to meet the rigorous ESD protection requirements recommended by the IEC61000-4-2 standard, as well as the surge protection requirements endorsed by the IEC61000-4-5 standard. In addition, the VE07P00231K has been designed to meet the requirement of MIL-STD-202F for increased ESD sturdiness.

Working Principles

When exposed to a surge of voltage, the TVS diode VE07P00231K quickly conducts current away from the protected components, rerouting it to ground. It also provides reverse bias potential across the protected component, withstanding high voltages and preventing destructive arcs across open circuits. To ensure fast response time and lower leakage current, the VE07P00231K has a relatively low breakdown voltage.

Once the surge is over, the device quickly returns to its off-state, providing a higher isolation voltage. In addition to surge protection, the TVS diode VE07P00231K also acts as a clamp, preventing the voltage on the protected component from exceeding the maximum designed voltage.

The VE07P00231K transient voltage suppressor diode is typically housed in a DO-204 package, which allows for easy mounting and a more efficient heat dissipation. The device is also RoHS (Restriction of Hazardous Substances) compliant and offers excellent surge protection, high reliability and cost-effectiveness.
