multicomp PRO Bipolar Transistor, Npn, 80V; Transistor Polarity Multicomp Pro BD179

The BD179 is an NPN bipolar transistor designed for medium power linear switching applications in a TO-126 package, measuring 7.4-7.8 mm in length, 10.5-10.8 mm in width, and 2.4-2.7 mm in thickness. It has a collector-emitter voltage rating of 80 V, a continuous collector current of 3 A, and a power dissipation of 1.25 W at 25°C, derating at 10 mW/°C above 25°C. The junction-to-ambient thermal resistance is 100°C/W, and the operating and storage junction temperature range is -65°C to +150°C. Current gain (hFE) ranges from 40 to 250 depending on collector current, with a transition frequency of 3 MHz. Collector-emitter saturation voltage and base-emitter on voltage are specified under pulse test conditions.
