3KP220-B Application Field and Working Principle

The 3KP220-B is a transient voltage surge suppressor (TVS) diode that is specifically designed to protect electronic equipment within industrial, communication, automotive and consumer applications from high voltage impulses. The V-I characteristics of these diodes makes them suitable for situations such as electric fast transients, electromechanical switching transients, inductive load switching, and steps in DC voltage.

The 3KP220-B is specifically intended to provide effective protection against Voltage transients on the power lines. It is suitable for applications such as lighting, motors, commutators, relays, and other switching arrangements. It provides a highly reliable and fast response to suppress transients from over voltage and under voltage and line noise with its low clamping voltage and low leakage current.

The working principle of this particular type of TVS diode is simple; it acts as a two-terminal semiconductor device that is triggered upon application of an over voltage at its legs. This causes the TVS diode to quickly act as a conductor. Therefore, reducing the maximum voltage that is allowed to pass through the circuit while clamping the voltage reduction at a certain level. The voltage clamping level is usually displayed with its particular VCmax model.

The 3KP220-B has a VCmax of 160 V, and its peak pulse power dissipation is 2.5 kW. It also has a non-repetitive peak pulse current of 180 A, which allows it to protect electronic components from damage at high voltage peak pulses, making it an ideal solution for most protection needs.

In conclusion, the 3KP220-B TVS diode is an ideal protection component for most industrial, communication, automotive and consumer applications. Its low clamping voltage and low leakage current make it suitable for applications such as electric fast transients, electromechanical switching transients, inductive load switching, and steps in DC voltage. Furthermore, its an effective solution to protect electronic components from damage at high voltage peak pulses.
