Features

  • Designed for use with NiH battery cells on spacecraft
  • Thermally activated non-dissipative permanent battery bypass
  • Charge/discharge diodes are replaced by a permanent low resistance short to bypass cell after open failure
  • Compact, rugged construction offers weight and cost savings
  • Can modify leads, available in different lengths
  • Radiation tolerant to 300 Mrad total dose
  • Discrete diodes screened and qualified per Microsemi PS11.50
  • Multiple shorting points for redundant short activation PART NUMBER SYMBOL MAX.
