The SMCJS series of high current uni/bi-directional transient

suppressors . These devices offer uni/bi-directional port protection from

15 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.
