2N3055 Bipolar (BJT) Single Transistor, NPN, 60 V, 800 kHz, 115 W, 15 A, 5 hFE

2N3055 transistors in an industry standard TO-3 case are used in a wide variety of audio, switching and power supply applications a heat sink is required to ensure that the transistor stays cool at high power levels.

Power dissipation - Pd = 115W at Tc = 25°C
DC current gain hFE = 20 ~ 70 at Ic = 4A
VCE(Sat) = 1.1V (max.) at Ic = 4A, IB = 400mA
Designed for use in general-purpose amplifier and switching applications
