The ESD3.3V02D-A is designed to protect voltage sensitive components
from ESD and transient voltage events. Excellent clamping capability, low
leakage, 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 cellular phones, MP3 players, digital cameras and
many other portable applications where board space is at a premium.
