1.5KE Series 1500W Transient Voltage Suppressor

V RRM = Repetitive peak reverse voltage
V DRM = Repetitive peak off state voltage
V RSM = Non repetitive peak reverse voltage (2)


The 1.5KE 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 6.8 volts to 600 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.
