ESDU3121
12 V Unidirectional ESD and
Surge Protection Device
The ESDU3121 is designed to protect voltage sensitive components
from ESD. Excellent clamping capability, low leakage, high peak
pulse current handling capability and fast response time provide best
in class protection on designs that are exposed to ESD. Because of its
small size, it is suited for use in cellular phones, tablets, MP3 players,
digital cameras and many other portable applications where board
space comes at a premium.
