ESD5621WXX
1-Line, Uni-directional, Transient Voltage Suppressor
http//:www.sh-willsemi.com
Descriptions
The ESD5621WXX is a uni-directional TVS (Transient
Voltage Suppressor). It is specifically designed to protect
sensitive electronic components which are connected to
power lines, from over-stress caused by ESD (Electrostatic
Discharge), EFT (Electrical Fast Transients) and Lightning.
The ESD5621WXX may be used to provide ESD protection
up to ±30kV (contact and air discharge) according to
IEC61000-4-2, and with high surge capability used to protect
USB voltage bus pin (8/20μs) according to IEC61000-4-5.
The ESD5621WXX is available in SOD-323F package.
Standard products are Pb-free and Halogen-free.
