DESCRIPTION
This DS9502 was designed as an additional ESD
protection for SRAM–based battery–buffered portable
memory modules. The memory chips used for these
modules have already a strong ESD–protection struc-
ture on their I/O line. Together with the DS9502 the ESD
protection level is raised to more than 27 kV (IEC 801–2
Reference model). In case of abnormal ESD hits
beyond its maximum ratings the DS9502 will eventually
fail “short” thus preventing further damage.
During normal operation the DS9502 behaves like a
regular 7.5V Zener Diode. When the voltage exceeds
the trigger voltage, the I/V characteristic of the device
will “snapback” allowing the same or higher amount of
current to flow, but at a significantly lower voltage. As
long as a minimum current or voltage is maintained, the
device will stay in the “snapback mode”. If the voltage or
the current falls below the holding voltage or holding
current, the device will abruptly change to its normal
mode and conduct only a small leakage current.
