DS9502 Key Features

  • Zener characteristic with voltage snap-back to protect against ESD hits
  • High avalanche voltage, low leakage and low capacitance avoid signal attenuation
  • patible to all 5V logic families
  • Space saving, low inductance TSOC surface mount package
  • Symmetric dual-port bondout to maximize energy dissipation in protection device
  • Industrial temperature range

DS9502 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).
