PD - 2.441A The 30BQ100 surface-mount Schottky rectifier has been de- signed for applications requiring very low forward drop and small foot prints on PC boards. Typical applications are in disk drives, switching power supplies, converters, free-wheeling diodes, battery charging and reverse battery protection.

  • Small footprint, surface mountable
  • Very low forward voltage drop
  • High frequency operation
  • Guard ring for enhanced ruggedness and long-term reliability Characteristics 30BQ100 Units IF(AV) Rectangular 3.0 A waveform VRRM 100 V IFSM @ tp = 5µs sine 2100 A VF @ 3.0Apk, TJ = 125°C 0.62 V TJ -55 to 175 °C Major Ratings and Characteristics Description / Features SMC CASE STYLE CASE OUTLINE
