Description

HUAREW High-quality BJT classification kit.

The principle of BJT (bipolar junction transistors): bipolar operation
Blocking layer transistors contain the simultaneous flow of
Electrons and holes.
So it is called bipolar, also bipolar carrier transistor
This operating mode is different from unipolar transistors
For example, only field effect transistors
Single type of carrier. The limit between two different dopants
The collection area is formed by a PN connection.

The use of BJT: bipolar transistors can control the signal
reinforce and have better
Power control, high-speed operation and durability,
Therefore, it is usually used for
Form amplifier circuits or drive speakers,
engines and other devices.
And is widely used in aerospace technology,
Medical devices and robots.
