Overview

SM30KWExxA/CA Series

The SM30KWExxA/CA Series are high-powered surface mount transient voltage suppression components designed to protect equipment and systems from the damaging effects of high voltage spikes. The surface mount package configuration provides a lower profile compared to legacy axial lead package configurations. These devices provide 30 kilowatts of peak pulse power dissipation for an 10/1000µs waveform. Applications include AC and DC power line protection, terrestrial base station protection as well as module lightning protection.
