PD - 2.480A The 20CJQ100 surface-mount Schottky rectifier has been designed for applications requiring very low forward drop and very small foot prints. Typical applications are in portables, switching power supplies, converters, automotive systems, free-wheeling diodes, battery charging and reverse battery protection.

  • Small footprint, surface mountable
  • Low profile
  • Very low forward voltage drop
  • High frequency operation
  • Guard ring for enhanced ruggedness and long-term reliability
