Working Principle

The JAN2N5682 is a three-terminal device and consists of two p-type layers separated by an n-type layer. The two p-type layers are the base and collector. The n-type layer is the emitter. When voltage is applied from the base, it attracts holes from the base layer and also electrons from the emitter layer to the base layer. These electrons and holes form a current loop and create a field in the junction, producing a voltage drop.

The ratio of the emitter current to the base current is called the current gain of the transistor. This current gain is determined by the resistances of the base and emitter layers. The higher the value of the resistance, the greater the current gain. When the collector is connected to the emitter, it creates a low-resistance path for the current flow and makes the current flow easier. This current flow is responsible for producing the power output from the JAN2N5682.

JAN2N5682 transistors are used for communication systems, power supplies, automotive electronics and other general-purpose applications. Its ability to switch large currents, low current gain and low voltage make it suitable for various applications.
