ESD5311Z
1-Line, Bi-directional, Ultra-low Capacitance
Transient Voltage Suppressors
http//:www.sh-willsemi.com
Descriptions
The ESD5311Z is an ultra-low capacitance TVS (Transient
Voltage Suppressor) designed to protect high speed data
interfaces. It has been specifically designed to protect
sensitive electronic components which are connected to data
and transmission lines from over-stress caused by ESD
(Electrostatic Discharge).
The ESD5311Z
incorporates
one pair
of
ultra-
low
capacitance steering diodes plus a TVS diode.
The ESD5311Z may be used to provide ESD protection up to
±20kV (contact discharge) according to IEC61000-4-2, and
withstand peak pulse current up to 4A (8/20μs) according to
IEC61000-4-5.
The ESD5311Z is available in DFN0603-2L package.
Standard products are Pb-free and Halogen-free.
