Radial Lead Transient Voltage Suppressors (TVS) KC Series Description The KC Series of high current transient suppressors have been specially designed for use in A.C. line protection and any demanding applications (AC or DC). 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. Features u Axial lead terminals u High current transient suppressor u Excellent Clamping Capability u Glass Passivated Junction u Bi-directional u Low Slope Resistance u Repetition Rate (duty cycle):0.01% u Hazardous Substances Free u RoHS Compliant u High Temperature soldering: 260°C/10 seconds at terminals u Epoxy Encapsulated u Silver plated leads u Solderable per MIL-STD-202 Method 208 Maximum Ratings Functional Diagram Bi-directional (TA=25℃ unless otherwise noted) Parameter Operating junction Storage Temperature Range Current Rating 1 Symbol Value Unit TJ -55 to +150 °C TSTG -55 to +150 °C IPP 10 KA Notes: 1.
