ESD5451XZ
1-Line, Bi-directional, Transient Voltage Suppressors
http//:www.sh-willsemi.com
Descriptions
The ESD5451XZ is a bi-directional TVS (Transient Voltage
Suppressor). It is specifically designed to protect sensitive
electronic components which are connected to low speed
data lines and control lines from over-stress caused by ESD
(Electrostatic Discharge), EFT (Electrical Fast Transients)
and Lightning.
The ESD5451XZ may be used to provide ESD protection up
to
±30kV
(contact
and
air
discharge)
according
to
IEC61000-4-2, and withstand peak pulse current up to 8A
(8/20μs) according to IEC61000-4-5.
The ESD5451XZ is available in FBP0603-2L package.
Standard products are Pb-free and Halogen-free.
