Description

The ESDALCxxxWx 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.

Features

■ 4 Unidirectional Transil functions

■ Breakdown voltage: VBR = 6.1 V minimum

■ Low leakage current: < 1 µA

■ Low capacitance: 7.5 pF at 3 V

■ Very small PCB area

Main applications

Where transient overvoltage protection in ESD sensitive equipment is required, such as :

■ Computers

■ Printers

■ Communication systems

■ Cellular phones and accessories

■ Wireline and wireless telephone sets

■ Set top boxes
