SMAJ400A - 400W TVS Diodes

Download the SMAJ400A datasheet PDF. This datasheet also covers the SMAJ5.0A variant, as both devices belong to the same 400w tvs diodes family and are provided as variant models within a single manufacturer datasheet.

General Description

The SMAJ series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

Key Features

  • 400W Peak Pulse Power capability at 10/1000µs waveform, repetition rate (duty cycle): 0.01%.
  • Excellent clamping capability.
  • Typical IR less than 1μA when VBR min>12V.
  • Surface mount footprint for compact PCB layout.
  • Low profile package.
  • Typical failure mode is short from over-specified voltage or current.
  • Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c.
  • IEC-61000-4-2 ESD 30kV(Air), 30kV (Contact).
  • ESD protection of data lin.
