ESDALC6V1Px

Low capacitance Transil™ arrays for ESD protection

Features

■ 2 to 4 unidirectional Transil functions

■ Breakdown voltage V

= 6.1 V min.

■ Low leakage current < 100 nA

■ Low capacitance (7.5 pF @ 3 V)

■ Very small PCB area < 2.6 mm

Benefits

■ High ESD protection level

■ High integration

Complies with the following standards

■ IEC 61000-4-2 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.
