■ Very small PCB area < 2.6 mm
Description
The ESDALC6V1Px are monolithic suppressors
designed to protect components connected to
data and transmission lines against ESD.
These devices clamp the voltage just above the
logic level supply for positive transients and to a
diode drop below ground for negative transients.
Benefits
■ High ESD protection level
■ High integration
Complies with the following standards:
IEC61000-4-2 level 4:
15 kV(air discharge)
8 kV(contact discharge)
MIL STD 883E-Method 3015-7: class3
25 kV HBM (Human Body Model)

In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a lead-free second level interconnect. The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com.
