Application Scenarios & Design Considerations

PNP Epitaxial Silicon Transistor

Alternative Part Number

  • 2SC2073 --: NPN power transistor with similar voltage and current ratings, commonly used as a substitute for the KSA940 in audio and general-purpose amplifier circuits.
  • MJE340 --: High-voltage NPN transistor with comparable Vceo and power dissipation, widely available and suitable for similar linear amplifier applications.
  • BD139 --: Popular NPN power transistor with adequate voltage and current ratings for many circuits that use the KSA940, though pinout and thermal ratings should be verified.
