ESD Protection Diodes with Ultra−Low

Capacitance

The ESD7951 is designed to protect voltage sensitive components that

require ultra−low capacitance from ESD and transient voltage events.

Excellent clamping capability, low capacitance, 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 low capacitance, it is

suited for use in high frequency designs such as USB 2.0 high speed and

antenna line applications.
