Key Features

  • 600W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycles):0.01%.
  • Excellent clamping capability.
  • Low incremental surge resistance.
  • Typical IR less than 1μA when VBR min>12V.
  • Optimized surface mount footprint for minimal PCB space impact.
  • Low profile package.
  • Typical failure mode due to exceeding maximum ratings is a short circuit condition.
  • Whisker test conducted based on Table 4a and 4c of JE.
