ESDAxxSCx

Quad Transil™ array for ESD protection

Features

Benefits

Complies with the following standards:

– 15 kV (air discharge)

– 8 kV (contact discharge)

– human body model

Applications

Where transient overvoltage protection in ESD

sensitive equipment is required, such as :

Description

The ESDAxxSC5 and ESDAxxSC6 are monolithic

voltage suppressors designed to protect

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.
