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)
Applications
Where transient overvoltage protection in ESD
sensitive equipment is required, such as:
■ Computers
■ Printers
■ Communication systems
■ Cellular phone handsets and acessories
■ Wireline and wireless telephone sets
■ Set-top boxes
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.
