TVS - diode is an abbreviation of Transient Voltage Suppressor diode, it is a general power semiconductor device designed to protect sensitive electrical components from voltage transients generated in a circuit. The 3KP220A is a monolithic-integrated overvoltage protection diode designed for protection of sensitive electronics from high-voltage transients induced by electrostatic discharge (ESD), lightning and other transient voltage events.

The 3KP220A consists of a single diode, which shorts high voltage signals to ground when the voltage exceeds the specifiedMaximum Working Voltage (MWV). It is designed to protect from overvoltage situations such as ESD transients, voltage transients, surge current. The 3KP220A works by absorbing the surge current and clamping the voltage to safe levels. It is easy to implement in a circuit and has a low power consumption.

It has an operating voltage of up to 220V and a peak surge current of 22A with a breakdown voltage of 26V. The 3KP220A has a high surge capability due to its low leakage and clamping current. It also has a fast response time and high insulation resistance, which makes it appropriate for high-frequency applications. The operating temperature range is -40 to +125 degrees Celsius.

The 3KP220A is used in a wide range of applications, from system level protection to high-speed data interfaces. It can also be used in consumer electronics, safety critical systems, automotive electronics and power supplies. In system level protection, the 3KP220A is used to protect sensitive circuit components from voltage transients associated with lightning, ESD and other high energy events. In high-speed data interfaces, the 3KP220A is used to protect critical data from EMF and EMI-induced transients. In automotive electronics, it is used to protect the power supplies from overvoltage conditions.

The working principle of the 3KP220A is that the diode shorts the high-voltage signals to ground when the voltage exceeds the specified Maximum Working Voltage (MWV). The diode operates in a zener breakdown mode and clamps the voltage to the MWV, thus protecting the attached circuit from voltage transients. The device is designed to offer a fast response time for transient overvoltage protection and to minimize stress on the protected circuit components.

In summary, the 3KP220A is a monolithic-integrated overvoltage protection diode designed to offer fast protection from transient events in power supplies, consumer electronics, safety critical systems and automotive electronics. It operates by absorbing the surge current and clamping the voltage to safe levels. It has a high surge capability, low power consumption, low leakage and clamping current, and a fast response time.
