DESCRIPTION
This series of Transient Voltage Suppressor (TVS) devices is packaged in
a ceramic, dual-in-line, hermetically sealed package. These components
offer 15 protective devices, unidirectional or bidirectional, common buss
connections, per package. The dual-in-line is designed specifically for data
line protection, at the PC board level. TTL and MOS voltage levels are
available for protection of input/output data circuits. Microsemi also offers
numerous other TVS products to meet higher and lower power demands
and special applications.

“C” suffix denotes bidirectional and “A” suffix provides a lower selected clamping voltage tolerance
NOTE 1:
A TVS is normally selected according to the reverse “Stand Off Voltage” V
WM
which should be equal to
or greater than the dc or continuous peak operating voltage level.
