Application Scenarios & Design Considerations

Audio Frequency High Frequency Power Amplifier

Alternative Part Number

  • 2SC2690A-Y --: Same transistor type and gain rank; Toshiba is the original developer of the 2SC2690A series, so electrical characteristics match closely.
  • 2SC5171-Y --: Similar NPN audio power transistor with comparable voltage and current ratings, suitable as a functional substitute in many circuits.
  • MJE15030 --: NPN power transistor with comparable voltage/current capability and widely available, usable where exact gain matching is not critical.
  • 2SC5171 --: Similar high-voltage, high-current NPN audio driver transistor with comparable Vceo and power ratings; widely used as a substitute in audio amplifier driver stages.
