onsemi Single Bipolar Transistors BD140

The BD140 is a silicon PNP bipolar transistor designed for audio amplification and driver applications in complementary circuits. It is packaged in a TO-225 case (77-09) with a maximum collector-emitter voltage of 80 V and a continuous collector current of 1.5 A. The device has a maximum power dissipation of 1.25 W at 25⁰C ambient temperature and 12.5 W at 25⁰C case temperature, with a thermal resistance from junction to case of 10 ⁰C/W and junction to ambient of 100 ⁰C/W. It is RoHS compliant and Pb-free, with an operating junction temperature range of -55⁰C to +150⁰C.
