Working Principle

A bipolar junction transistor (BJT) is a type of transistor that has two p-n junctions. These junctions are made up of different doped regions, and can be either N-type (n-channel) or P-type (p-channel). These junctions can be connected in either a common-emitter or a common-base configuration.

In a BJT, current flows from the emitter to the collector through one of the junctions, and voltage is applied across the other junction. The voltage applied to the base determines the current that flows through the transistor, with a larger voltage leading to higher levels of current. This process is known as “current control” and is the basis of the operation of a BJT.

The BUJ403A,127 transistor has a maximum collector-emitter voltage rating of 25 volts, and can handle up to 10 amperes of collector current. It has a high gain, and is popular in a range of applications due to its relatively low production cost, good performance, and well-defined electrical characteristics.
