ESD5431N
1-Line, Bi-directional, Transient Voltage Suppressors
http//:www.sh-willsemi.com
Descriptions
The ESD5431N is a bi-directional TVS (Transient Voltage
Suppressor). It is specifically designed to protect sensitive
electronic components which are connected to power lines,
low speed data lines and control lines from over-stress
caused by ESD (Electrostatic Discharge), EFT (Electrical
Fast Transients) and Lightning.
The ESD5431N may be used to provide ESD protection up to
±30kV (contact discharge) according to IEC61000-4-2, and
withstand peak pulse current up to 10A (8/20μs) according to
IEC61000-4-5.
The ESD5431N is available in DFN1006-2L package.
Standard products are Pb-free and Halogen-free.
