TVS – Diodes : MP4KE120CA Application Field and Working Principle

TVS – diodes are gaining more attention in the current days, due to their applications in a range of electrical equipment and devices. From computers and peripherals to wireless receivers, TVS – diodes are essential components for the protection of sensitive equipment. MP4KE120CA is one of the most popular diode models, and offers robust circuit protection in an easy-to-install package.

Application Field of MP4KE120CA

MP4KE120CA is ideal for using in many electronic products, as its designed for the lightning protection of I/O ports, data lines and sensitive components. It can effectively protect the circuit from different kinds of over-voltage threats, such as ESD, EFT, and lightning. Besides, it can easily fit for the circuit, as its size is much smaller compared to current MOVs orvaristors.

Working Principle of MP4KE120CA

Like other transil diodes, MP4KE120CA absorbs energy when the over-voltage threats happen. It is designed for having a reverse stand-off voltage (VRWM) of 12V, 5KA repetitive peak pulse power (PPP) of 25W, and a clamping voltage (VC) of 18V, which all provide excellent performance in ESD, EFT, and lightning surge test. When the voltage amplitude of the signal line is beyond the breakdown voltage of the diode, the over-voltage will be clamped by its active component. In addition, the clamp voltage of the diode, as well as the capacitance of the devices, will limit the peak current and voltage of the signal line.

MP4KE120CA can provide reliable surge protection solutions for different electronics devices, including computers, radio systems, LED lighting, consumer electronics, and more. With its wide application range and superior performance, this type of diode has become increasingly adopted in today’s electrical system.
