SRDA3.3 - TVS Diode Arrays

Download the SRDA3.3 datasheet PDF. This datasheet also covers the SRDA3.3-4BTG variant, as both devices belong to the same tvs diode arrays family and are provided as variant models within a single manufacturer datasheet.

General Description

The SRDA3.3 integrates low capacitance rail-to-rail diodes with an additional zener diode to protect I/O pins against ESD and lightning induced surge events.

Key Features

  • Lightning protection, IEC61000-4-5, 35A (8/20μs).
  • EFT, IEC61000-4-4, 50A (5/50ns).
  • ESD, IEC61000-4-2, ±30kV contact, ±30kV air.
  • Low clamping voltage.
  • Low leakage current.
  • SOIC-8 surface mount package (JEDEC MS-012).

TVS Diode Arrays (SPA® Diodes) Lightning Surge Protection- SRDA3.3 Series SRDA3.3 Series 8pF 35A Diode Array RoHS Pb GREEN Description The SRDA3.3 integrates low capacitance rail-to-rail diodes with an additional zener diode to protect I/O pins against ESD and lightning induced surge events. This device can safely absorb up to 35A per IEC61000-4-5 (tp=8/20μs) without performance degradation and a minimum ±30kV ESD per IEC61000-4-2 international standard. Its low loading capacitance makes it ideal for high-speed interfaceprotection.
