Working Principles

The PL502-35OI is a bipolar junction transistor (BJT) that operates as an amplifier. It consists of three layers of semiconductor material: the emitter, base, and collector. When a small input signal is applied to the base-emitter junction, it controls the larger output current flowing through the collector-emitter junction. This amplification process allows weak signals to be boosted to a usable level.
