RCA TRANSISTOR MANUAL POWER TRANSISTOR Silicon n-p-n type used in a wide 8 ON] 48 4 variety of intermediate-power switch- ; ' ing and amplifier applications in in- dustrial and military equipment. It is used in power switching, de-to-de con- verter, inverter, chopper, solenoid and relay control circuits; in oscillator, regulator, and pulse-amplifier circuits; and as a class A or class B push-pull audio and servo amplifier. It features low saturation resistance, high current and power dissipation, high beta at high current, and excellent high-ternperature performance. JEDEC No. TO-8 package; outline 8, Outlines Section.
