The BD139 is a bipolar 80V 1A NPN transistor in a TO-126 case.

When power is applied to an NPN transistors control pin, the power will travel from the collector to the emitter. NPN transistors are used for switching to ground on devices.


  • Collector emitter voltage: 80V
  • Collector base voltage: 80V
  • Emitter base voltage: 5V
  • Collector current: 1A
  • Collector dissipation: 12W
  • Transition frequency: 50Mhz
  • Package: TO-126


  • 10 x BD139 80V 1A Bipolar NPN Transistors
