Power transistors are commonly used in power amplification and switch control circuits.
In 1952, researchers at Bell Laboratories in the United States first proposed the concept of PNP power transistors,
Darlington transistor is a high gain, high input impedance bipolar transistor configuration consisting of two transistors cascaded together. It can be used to amplify current and voltage
Higher saturation voltage drop: Due to the cascading effect,
Darlington transistors can be used as amplifiers to amplify small signals into large signals.
Current limitation: Darlington transistors have a high amplification factor,
