Calculate Darlington transistor configuration characteristics

Circuit Parameters

Darlington Considerations

  • • Higher Vbe drop (1.2-1.4V typical)
  • • Lower saturation voltage headroom
  • • Slower switching than single transistor
  • • Higher leakage current at high temps
  • • Excellent for high gain DC applications
