التطبيقات

  • Audio driver and output stages
  • Motor driver circuits
  • Medium-power switching
  • General-purpose amplification

The BD139-16 from onsemi is an NPN medium-power silicon transistor in a SOT-32 (TO-126) package. The -16 suffix indicates hFE group 16 (100-250 at 150mA), providing consistent gain for audio amplifier designs. Rated at 80V and 1.5A with 12.5W power dissipation, it fills the gap between small-signal transistors (BC547 at 100mA) and power transistors (TIP41C at 6A). The 190MHz transition frequency supports audio and medium-frequency applications. The complementary BD140-16 (PNP) enables push-pull and complementary circuit configurations. The SOT-32 package has a metal tab on the back for heatsink mounting, with the tab connected to the collector. The BD139 is one of the most commonly used transistors in DIY audio amplifiers, serving as a driver stage for larger output transistors like the TIP41C/TIP42C.

The BD139-16 is a silicon NPN epitaxial planar transistor. In active mode, base current controls collector current with gain (hFE) of 100-250. The -16 group selects transistors with hFE between 100 and 250, ensuring matched pairs can be selected for push-pull amplifiers. For switching applications, the transistor is driven into saturation by providing IB > IC/hFE(min), reducing VCE to VCE(sat) of approximately 0.5V at 500mA. The 190MHz transition frequency provides adequate bandwidth for audio driver stages. In audio amplifier output stages, the BD139 drives the base of a larger power transistor (Darlington or emitter-follower configuration), providing voltage gain in the driver stage while the power transistor handles the current. The SOT-32 metal tab (collector) requires an insulating washer when mounting to a grounded heatsink.
