Transient Voltage Suppressors Array for ESD Protection
SMDAXXC-8 Series
Description
SOP-14
The SMDAxxC-8 series of transient voltage suppressors are
designed to protect components which are connected to data
and transmission lines from voltage surges caused by
electrostatic discharge (ESD), electrical fast transients (EFT),
and lightning.
TVS diodes are characterized by their high surge capability, low
operating and clamping voltages, and fast response time.
This makes them ideal for use as board level protection of
sensitive semiconductor components. The SMDAxxC-8 is
designed to provide transient suppression on multiple data lines
and I/O ports. The low profile SOP-14 design allows the user to
protect up to eight data and I/O lines with one package. They
are bidirectional device and may be used on lines where the
normal operating voltage is above and below ground (i.e. -12V
to +12V).
