Working principle of the 2SC5086-O,LF

The 2SC5086-O,LF works based on the principle of a bipolar junction transistor. Bipolar junction transistors are three terminal devices composed of two PN junctions connected in series, one of which is used as a base and the other as an emitter. The two junctions are connected at a common point, making up the third terminal, the collector. The current flows from the emitter to the collector when a voltage is applied to the base, resulting in current amplification. In the case of the 2SC5086-O,LF, the built in bias voltage oscillator provides an optimal bias point for optimal performance in RF amplifier designs.
