BD140 PNP TRANSISTOR

The BD140 is a PNP Power Transistor, designed to be the complementary counterpart to the NPN BD139, and is typically housed in a TO-126 package.

Its key ratings are:

• Maximum Collector Current: 1.5 A.

• Maximum Collector-Emitter Voltage: 80 V.

• Maximum Power Dissipation: 12.5 W at 25C.

• DC Current Gain h_FE: Typically ranges from 40 to 250

It is widely used in complementary symmetry stages (alongside the BD139) for audio amplifiers, as well as in general purpose medium-power switching and driver applications.
