Power bipolar transistors are semiconductors in which a base n-type or p–type layer is sandwiched between emitter and collector layers of the opposite type. There are two polarities available: PNP and ...

NPN transistors have collector and emitter leads made of N-type material and a base ... Bipolar transistors are preferred for high speed switching applications and as high-power amplifiers for systems ...

This transistor switching circuit uses an npn transistor, a voltage divider (consisting of a \(5 kΩ \) resistor and thermistor) and a \(5 V\) power supply. Use the information in the table to ...
