DS9502 Overview
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).
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
