SMDA05C THRU SMDA24C
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.
