The BUX85G is a high-voltage NPN silicon power transistor from onsemi, specifically designed for switch-mode power applications such as converters, inverters, switching regulators, and motor control systems. It features a collector-emitter sustaining voltage (VCEO(sus)) of 450V, a continuous collector current (IC) of 2A, and a peak collector current of 3A. The device can dissipate up to 50W at a case temperature of 25°C, with a derating factor of 0.4W/°C above 25°C.
Key electrical characteristics include a minimum DC current gain (hFE) of 30 at Ic=100mA, Vce=5V, a maximum collector-emitter saturation voltage of 1V at Ib=200mA, Ic=1A, and a minimum transition frequency (fT) of 4MHz at Ic=500mA, Vce=10V. The switching speeds are specified with typical turn-on time of 0.3µs, storage time of 2µs, and fall time of 0.3µs under test conditions Vcc=250V, Ic=1A.
The BUX85G is housed in the industry-standard TO-220-3 package (TO-220) with through-hole mounting, providing a junction-to-case thermal resistance of 2.5°C/W and junction-to-ambient of 62.5°C/W. The operating junction temperature range is -65°C to 150°C. The device is Pb-Free and RoHS compliant, making it suitable for environmentally conscious designs.
