Application Scenarios & Design Considerations

Audio Frequency Power Amplifier

Alternative Part Number

  • 2SD882 --: NPN power transistor with similar 30V/3A ratings and complementary PNP 2SB772, a direct functional replacement for the KSB772-Y.
  • MJE172 --: PNP medium-power transistor rated 60V/3A, suitable substitute for general switching and amplifier applications where the KSB772-Y is used.
  • BD140 --: Widely available PNP power transistor rated 80V/1.5A, acceptable alternative for lower-current applications with similar package style.
  • 2SD882-Y --: NPN power transistor with similar Vceo (~30V) and current rating (~3A), commonly used as a direct substitute for the KSB772 in audio and switching applications.
