NOTE1: The SAC series is a low capacitance silicon transient voltage suppressor for data or signal lines. It is designed for
commercial and industrial applications. This series offers pricing, size, and capacitance advantages. This series employs a
standard TVS in series with a rectifier which reduces the effective capacitance up through 70MHz with a minimum
amount of signal loss or deformation. If bidirectional transient protection capability is required, two low capacitance TVS
must be used in parallel, opposite in polarity for complete AC protection.
NOTE2: The SAC series of low capacitance silicon transient voltage suppressors, rated at 400 watts, provides board level
protection for data or signal lines form the damaging effects of electrostatic discharge(ESD), and electromagnetic pluse
(EMP).It will clamp the inductive overshoot voltage caused by very fast impulse rise times. The low capacitance assures
minimum signal attenuation.
NOTE3： A TVS is normally selected according to the reverse " Stand Off Voltage" (VR) which should be equal to or greater than the
DC or continuous peak operating voltage level
