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
TRANSILARRAY
FOR ESD PROTECTION
FEATURES
18 BIDIRECTIONAL TRANSILFUNCTIONS
LOW CAPACITANCE : C = 30pF @ VRM
500 W peak pulse power (8/20 µs)
DESCRIPTION
The ESDA25DB3 is a dual monolithic voltage
suppressor designed to protect componentswhich
are connected to data and transmission lines
against ESD.
BENEFITS
High ESD protection level : up to 25 kV
High integration
Suitable for high density boards
