ESD54291Z05
Will Semiconductor Ltd. 1 Revision 1.1, 2019/01/25
ESD54291Z05
1-Line, Bi-directional, Transient Voltage Suppressors
Descriptions
The ESD54291Z05 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 ESD54291Z05 may be used to provide ESD protection
up to ±20kV (contact and air discharge) according to
IEC61000-4-2, and withstand peak pulse current up to 3A
(8/20μs) according to IEC61000-4-5.
The ESD54291Z05 is available in DFN0603-2L package.
Standard products are Pb-free and Halogen-free.
