The GESDS12VD1F1 is designed to protect voltage sensitive electronic components
from ESD and other transients. Excellent clamping capability, low leakage, low capacitance,
and fast response time, make these parts ideal for ESD protection on designs where board
space is at a premium. Because of its small size, it is suited for use in digital cameras, cellular
phones, MP3 players and many other portable applications where board space is at a
premium.
