§ Industrial temperature range

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.
