ON ESDR0502BT1G Transient voltage suppressor esd protection diodes with ultra−low capacitance Datasheet

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.

AND8308/D − Interpretation of Datasheet Parameters
for ESD Devices.
systems such as cell phones or laptop computers it is not
clearly defined in the spec how to specify a clamping voltage
at the device level. ON Semiconductor has developed a way
to examine the entire voltage waveform across the ESD
protection diode over the time domain of an ESD pulse in the
form of an oscilloscope screenshot, which can be found on
the datasheets for all ESD protection diodes. For more
information on how ON Semiconductor creates these
screenshots and how to interpret them please refer to
AND8307/D.
ESD Voltage Clamping
For sensitive circuit elements it is important to limit the
voltage that an IC will be exposed to during an ESD event
to as low a voltage as possible. The ESD clamping voltage
is the voltage drop across the ESD protection diode during
an ESD event per the IEC61000−4−2 waveform. Since the
IEC61000−4−2 was written as a pass/fail spec for larger
