BD140 is a three layer NPN or PNP device within the working range, the collector current IC is a function of the base current IB, a change in the base current giving a corresponding amplified change in the collector current for a given collector emitter voltage VCE.


• Low saturation voltage

• Simple drive requirements

• High safe operating area

• For low distortion complementary designs

• Easy to carry and handle
