onsemi Single Bipolar Transistors BUL147

The BUL147 is an NPN bipolar power transistor designed for switchmode power supply and fluorescent lamp ballast applications up to 180 watts. It is available in a TO-220AB package with dimensions of 14.48 to 15.75 mm in length, 9.66 to 10.28 mm in width, and 5.97 to 6.47 mm in height. The device has a collector-emitter sustaining voltage of 400 Vdc, a continuous collector current rating of 8.0 Adc, and a peak current rating of 16 A under pulse conditions. It dissipates up to 125 W at 25°C with a thermal resistance from junction to case of 1.0°C/W. The BUL147 meets RoHS compliance and is available in a Pb-free variant. It operates with a junction temperature range of -65°C to 150°C.
