STMicroelectronics ESDA6V1P6 Transilâ ¢ array for esd protection Datasheet

ESDAxxxP6
ASD
Transil™ array for ESD protection
Main applications
Where transient overvoltage protection in ESD
sensitive equipment is required, such as:
■
Computers
■
Printers
■
Communication systems and cellular phones
■
Video equipment
These devices are particularly adapted to the
protection of symmetrical signals.

Description
The ESDAxxxP6 are monolithic arrays designed
to protect up to 5 lines against ESD transients.
Figure 2.
These devices are ideal for situations where both
reduced line capacitance and board space saving
are required.

In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a lead-free second level interconnect. The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com.
