The 3KP series of high-current uni/bi-directional transient suppressors are designed for A.C. line protection and high-power DC bus clamping applications. These devices offer uni/bi-directional port protection from 5.0 volts to 220 volts. They provide a clamping voltage lower than the avalanche voltage; therefore, any voltage rise due to increased current conduction is contained to a minimum, providing the best possible protection level. They can also be connected in series and/or parallel to create very high-capacity protection solutions.
