About Bipolar Transistor
Single bipolar transistors are fundamental semiconductor devices used in electronic circuits for various purposes, such as amplification or switching. They come in two main types: NPN (negative-positive-negative) and PNP (positive-negative-positive), referring to the arrangement of the semiconductor layers.
NPN Transistor: In an NPN transistor, a thin layer of P-type semiconductor material is sandwiched between two layers of N-type semiconductor material. It has three terminals: the emitter (N-type), the base (P-type), and the collector (N-type). When a small current flows between the base and the emitter, it controls a larger current flowing between the collector and the emitter. NPN transistors are commonly used in amplification circuits.
PNP Transistor: A PNP transistor is constructed with a thin layer of N-type semiconductor material between two layers of P-type semiconductor material. Like the NPN transistor, it also has three terminals: the emitter (P-type), the base (N-type), and the collector (P-type). When a small current is applied from the base to the emitter, it controls the larger current flowing from the collector to the emitter. PNP transistors are often used in applications like switches and amplifiers as well.
