DS9502 ESD Protection Diode

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 bey.
