SPE0521
Single-Line ESD Protection Array
DESCRIPTION
The SPE0521 are designed by TVS bi-direction device 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. SPE0521 will protect
single line, and may be used on line where the signal
polarities swing above and below ground.
SPE0521 offer desirable characteristics for board level
protection including fast response time, low operating and
clamping voltage, and no device degradation.
SPE0521 may be used to meet the immunity requirements
of IEC 61000-4-2, level 4. The small SOD-523 package
makes them ideal for use in portable electronics such as
cell phones, PDA’s, notebook computers, and digital
cameras.
