Application Scenarios & Design Considerations

NPN Epitaxial Silicon Darlington Transistor

Alternative Part Number

  • BDX33C --: NPN Darlington power transistor with similar 100V/10A ratings and complementary BDX34C, a common drop-in for TIP142 applications.
  • 2N6045 --: NPN Darlington transistor rated 100V/8A in TO-220, widely used as an alternative to TIP142 in switching and amplifier circuits.
  • MJD127 --: NPN Darlington in DPAK package with 100V/8A rating; suitable when a surface-mount equivalent of TIP142 is acceptable.
