DESCRIPTION
The ESDAxxSC5 and ESDAxxSC6 are monolithic
voltage
components which are connected to data and
transmission lines against ESD.
They clamp the voltage just above the logic level
supply for positive transients, and to a diode drop
below ground for negative transient.
BENEFITS
High ESD protection level : up to 25 kV
High integration
Suitable for high density boards
COMPLIES WITH THE FOLLOWING STAN-
DARDS:
IEC61000-4-2 : level 4
MIL STD 883C-Method 3015-6 : class3
