Output transistor

A single large bipolar transistor schematic symbol intended for use as an output-stage or mirror/amplifier output device. Drawn in clean, bold black schematic lines with a wider, heavier footprint than a small-signal transistor to suggest power handling. The symbol has three clearly visible terminals labeled or visually identifiable as collector, base, and emitter, with a standard collector-base-emitter geometry and a clearly visible emitter arrow indicating npn or pnp type. Collector and emitter leads may be slightly thicker or longer than usual to reinforce the sturdy, high-current appearance. Compact enough to function as a reusable circuit block, but visually more substantial than an ordinary small-signal transistor.
