The Clamp
tect sensitive electronics from damage or latch-up due
to ESD. They are designed for use in applications where
board space is at a premium. Each device requires less
than 2.9mm
lines. They are unidirectional devices and may be used
on lines with positive signal polarities.
The clamp
prietary EPD process technology. The EPD process pro-
vides low standoff voltages with significant reductions in
leakage currents and capacitance over silicon-avalanche
diode processes. They feature a true operating voltage
of 3.3 volts for superior protection when compared to
traditional pn junction devices.
These devices may be used to meet the immunity re-
quirements of IEC 61000-4-2, level 4. They offer desir-
able characteristics for board level protection including
fast response time, low operating and clamping voltage,
and no device degradation. The small SC89 package
makes them ideal for use in portable electronics such as
cell phones, PDAs, notebook computers, and digital cam-
eras.
