ESDA25DB3
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 RS232 I/O port
protection where the line interface withstands 2
kV, ESD surges.
