The BU426A is an NPN bipolar transistor designed for high-voltage switching applications in colour TV power supplies. It is packaged in a TO-247 case with dimensions ranging from 20.63 to 22.38 mm in length, 15.38 to 16.2 mm in width, and 1.9 to 2.7 mm in thickness. The device has a collector-emitter voltage rating of 400 V, a continuous collector current of 6 A, and a maximum power dissipation of 113 W at 25℃, derating at 0.904 W/°C above that temperature. The collector-emitter saturation voltage is 1.5 V maximum at 2.5 A collector current and 0.5 A base current. The current gain bandwidth product is 4 MHz, and thermal resistance from junction to case is 1.106 °C/W. Operating and storage junction temperatures range from -65°C to +150°C.
