Bidirectional TVS Array
for Protection of Four Lines
PROTECTION PRODUCTS
Description
The SMDAxxC series of TVS arrays are designed to
provide bidirectional protection for sensitive electronics
from damage or latch-up due to ESD, lightning and
other voltage-induced transient events. Each device
will protect four data or I/O lines. They are available
with operating voltages of 5V, 12V, 15V and 24V.
TVS diodes are solid-state devices designed specifically
for transient suppression. They offer desirable charac-
teristics for board level protection including fast re-
sponse time, low operating and clamping voltage and
no device degradation. The low profile SO-8 package
allows the user to protect up to four independent lines
with one package. The SMDAxxC series is suitable
protection for sensitive semiconductors components
such as microprocessors, ASICs, transceivers, trans-
ducers, and CMOS memory.
