ESDR0502B/D

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.
