SPE1244
3-Line ESD Protection Array
DESCRIPTION
The SPE1244 are designed by TVS array that is to protect
sensitive electronics from damage or latch-up due to ESD.
They are designed for use in applications where board
space is at a premium. SPE1244 will protect up to three
line, and may be used on lines where the signal polarities
swing above and below ground.
SPE1244 offer desirable characteristics for board level
protection including fast response time, low operating and
clamping voltage, and no device degradation.
SPE1244 may be used to meet the immunity requirements
of IEC 61000-4-2, level 4. The small SOT-143 package
makes them ideal for use in portable electronics such as
cell phones, PDA’s, notebook computers, and digital
cameras.
