Application Specific Discretes
A.S.D.
ESDAxxL
DUAL TRANSIL ARRAY
FOR ESD PROTECTION
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
n 2 UNIDIRECTIONAL TRANSIL FUNCTIONS.
n LOW LEAKAGE CURRENT : IR max. < 20µA at
VBR.
n 300 W PEAK PULSE POWER (8/20µs)
DESCRIPTION
The ESDAxxL is a dual monolithic voltage
suppressor designed to protect components which
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.
