The CESD3V3D5 thru CESD12VD5 are high energy, high ESD voltage EOS (electrical over-stress) protectors. The Devices are available with working voltage ratings that reflect the most commonly used design values of 3.3, 5.0, 7.0 and12.0 volts making them ideal for EOS protection of VBus and user interface applications. The CESD series of devices have a much lower idle current (efficiency) than MLVs, have a much tighter clamping ratio (VC/VRWM) for more precise protection and have no inherent “wear-out” mechanism as do MLVs that are subjected to multiple surge events over the product lifetime. The small package outline and low package profile make these devices suitable for space constrained applications.
