QUAL TRANSILO ARRAY FOR ESD PROTECTION

No Preview Available !

ESDAxxxWx
TRANSIL™ array for data protection
Main applications
Where transient overvoltage protection in ESD
sensitive equipment is required, such as :
Computers
Printers
Communication systems
Cellular phones handsets and accessories
Wireline and wireless telephone sets
Set top boxes
Features
2 up to 5 Unidirectional Transil functions
Breakdown voltage:
VBR = 6.1 V min. and 25 V min.
Low leakage current: < 1 µA
Very small PCB area < 4.2 mm2 typically
Description
The ESDAxxxWx are monolithic suppressors
designed to protect components connected to
data and transmission lines against ESD.
These devices clamp the voltage just above the
logic level supply for positive transients, and to a
diode drop below ground for negative transients.
Benefits
High ESD protection level: up to 25 kV
High integration
Complies with the following standards
IEC61000-4-2
Level 4
15 kV (air discharge)
8 kV(contact discharge)
MIL STD 883E - Method 3015-7 Class 3
25 kV HBM (Human Body Model)
