The ESD4.5V32D-HA 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.
