TRANSIL™ ARRAY FOR ESD PROTECTION

STMicroelectronics 

®

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 RS232 I/O port

protectionwhere the line interfacewithstands 2 kV,

ESD surges.

ESDA25DB3

TRANSIL™ ARRAY
