ESDR0502B Datasheet, PDF (1/4 Pages) ON Semiconductor – Transient Voltage Suppressor ESD Protection Diodes with Ultra−Low Capacitance
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.

DEVICE MARKING INFORMATION
See specific marking information in the device marking
column of the Electrical Characteristics tables starting on
page 2 of this data sheet.
Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
