Circuit Protection

Transient Voltage Suppressors (TVS)
Any electrical or electronic product that requires connection to a mains supply system requires some form of TRANSIENT VOLTAGE PROTECTION. Even domestic electricity supplies can exhibit voltage spikes up to 800v and even though their duration is often only nano seconds they can permanently damage any connected appliance. SiPower has the most comprehensive range of transient voltage suppressors in the industry. Breakdown voltages available from 5 volt to 600 volts in axial or surface mount packaging.
