The full name of bipolar transistor is bipolar junction transistor, also known as Transistor, is an electronic device with three terminals, made of three parts of semiconductors with different degrees of doping, the flow of charge in the transistor is mainly due to Diffusion and drift motion of carriers at the PN junction.

Bipolar transistors can improve high transconductance and output resistance, and have high-speed, durable characteristics, and have outstanding capabilities in power control. Therefore, bipolar transistors are important components for composing analog circuits, especially VHF application circuits such as radio frequency circuits in wireless communication systems.

Bipolar transistors can amplify signals, and have good power control, high-speed operation and durability, so they are often used to form amplifier circuits, or drive speakers, motors and other equipment, and are widely used in aerospace engineering, Products in fields such as medical devices and robotics.
