P8S28CA

P8S Series 8000W Transient Voltage Suppressor DESCRIPTION: The P8S 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 20 volts to 43 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. Symbol FEATURES:          Low zener impedance. Excellent clamping capability. JEDEC R-6/P-600 Molded Plastic. Repetition rate (duty cycle): 0.01%. Color band denoted cathode except bidirectional. High temperature soldering: 260℃/10s at terminals. Glass passivated chip junction in R-6/P600 package. 8000W Peak Pulse power capability at 10×1000μs waveform. Fast response time: typically less than 1.0ps from 0V to VBR min.  AEC-Q101 qualified.
