V390CH8 is one of the latest series of Transient Voltage Suppression (TVS) diodes from Vishay. It is designed to protect sensitive equipment from electrical overstresses that can be caused by electrostatic discharges (ESD), electrical fast transients (EFT), lightning, and other similar events. The device is a surge protection component that uses metal-oxide varistor (MOV) technology, and it is capable of providing up to 880 watts peak power dissipation with a clamping voltage of 390 volts. The V390CH8 is available in either through-hole or surface mount packages.

TVS diodes are components that can protect electronics from transient voltage surges, which are momentary, extreme increases in voltage. The V390CH8 can dissipate up to 880 watts of peak power and clamp at a voltage of 390 volts. This means that for extreme voltage surges, the device will absorb the energy, protecting the components of the circuit from the negative effects of the transient voltage. The device will not degrade due to repeated surges, so it is suitable for use in applications where periodic over-voltage events are likely.

The working principle of the V390CH8 is based on MOV technology. MOVs are composed of metal-oxide cores, which act like variable resistors, changing resistance in response to the voltage applied across them. When the voltage across an MOV exceeds the breakdown voltage of the device, it will allow a large current to flow, quickly reducing the voltage across it. The V390CH8 is specifically designed to offer a low clamping voltage so that it can react quickly to high voltage surges. The device also features an ultra-low inductance of 2.4 nH (nanoseconds) and a fast response time of less than 10 ns.

The V390CH8 is highly suitable for use in a broad range of applications, such as automotive, consumer electronics, and other industrial and commercial applications. It can be used to provide surge protection for sensitive low voltage circuits, data lines, power lines, communication lines, or any other type of digital logic circuits. The device is available in through-hole or surface mount packages, making it easy to integrate into most existing designs. Additionally, the device meets international safety standards such as UL Flammability Rating, UL 481, and IEC 60950-1.

In summary, the V390CH8 is a specialized TVS diode designed for protector sensitive equipment from transient voltage surges. The device is based on MOV technology and features a low clamping voltage of 390 volts and 880 watts peak power dissipation. The device is highly suitable for use in many types of applications, and it is available in through-hole and surface mount packages. The V390CH8 meets many international safety standards and is designed for reliable long term protection of sensitive circuitry.
