ESDR0502B
Transient Voltage Suppressor
ESD Protection Diodes with Ultra ? Low
Capacitance
The ESDR0502B is designed to protect voltage sensitive
components from damage due to ESD in applications that require ultra
low capacitance to preserve signal integrity. Excellent clamping
capability, low leakage and fast response time are combined with an
ultra low diode capacitance of 0.5 pF to provide best in class

protection from IC damage due to ESD. The small SC ? 75 package is
ideal for designs where board space is at a premium. The ESDR0502B
can be used to protect two uni ? directional lines or one bi ? directional

line. When used to protect one bi ? directional line, the effective
capacitance is 0.25 pF. Because of its low capacitance, it is well suited
for protecting high frequency signal lines such as USB2.0 high speed
and antenna line applications.
