Application Scenarios & Design Considerations

General Purpose Amplifier and Switching Applications

Alternative Part Number

  • 2N6124 --: NPN power transistor with similar 80V/4A ratings and TO-220 package, direct functional replacement for general switching and amplifier use.
  • MJE3055T --: NPN power transistor rated 60V/10A in TO-220, higher current capability than TIP31B, widely available and suitable for similar switching/amplifier applications.
  • BD241C --: NPN power transistor rated 100V/3A in TO-220, close electrical match to TIP31B with adequate voltage margin for most replacement designs.
