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
structure 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.
