ESDAxxL
Application Specific Discretes
A.S.D.
APPLICATIONS
Where transient overvoltage protection in ESD
sensitive equipment is required, such as :
- COMPUTERS
- PRINTERS
- COMMUNICATION SYSTEMS
It is particulary recommended for the RS232 I/O
port protection where the line interface withstands
only with 2kV ESD surges.
FEATURES
2 UNIDIRECTIONAL TRANSIL FUNCTIONS.

DESCRIPTION
The ESDAxxL is a dual monolithic voltage
suppressordesignedtoprotectcomponentswhich
are connected to data and transmission lines
against ESD.
It clamps the voltage just above the logic level
supply for positive transients, and to a diode drop
below ground for negative transients.
It can also work as bidirectionnal suppressor by
connecting only pin1 and 2.
