Lightning & ESD Protection For Gigabit Ethernet Interface
Low Capacitance
ULC33CP8
Description
DFN2010P8
The ULC33CP8 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.
