2N6099 NPN General Purpose Transistor

The 2N6099 is a silicon NPN power transistor housed in the TO-220 package, built for general-purpose amplifier and switching duty where both moderate voltage headroom and high current capability are needed. It carries a 10A collector current rating and a 75W power dissipation figure, putting it in the same class as parts used for motor drivers, linear regulators, and audio power stages.

With a 60V collector-emitter / 70V collector-base rating, the 2N6099 is not intended for mains-level switching, but comfortably covers most low-voltage DC power circuits. Its hFE of 20–80 is on the lower side typical of power transistors, so base-drive current needs to be sized accordingly in switching designs.
