The 2N6228 is a low power, small size NPN transistor. It has two main applications, which are switching and amplifying, and it works on the principle of transistor action. This article will cover the application fields and working principle of 2N6228 single bipolar (BJT).

Application Fields of 2N6228:

The 2N6228 can be used in both switching and amplifying applications. For switching applications, it can be used to switch low-power loads like small relays, lamps and LEDs, and also as a small signal switch. For amplifying applications, it has low power output of 1 Watt and is therefore excellent for use in low power audio amplifiers, radio frequency amplifiers and small audio amplifiers.

Working Principle of 2N6228:

The 2N6228 has two main terminals: the base and the collector. A small current through the base is used to control the flow of current through the collector/emitter junction, which is the principle of transistor action. In an NPN transistor like the 2N6228, the current flows from the collector to the emitter when a voltage is applied to the base. This allows current to be switched on and off using the switch function of the transistor.

The 2N6228 can be used as a small signal switch or amplifier by connecting the base to a signal (like an audio signal) and the emitter to ground. When the signal level rises above a certain level, the base current will increase and the collector current will flow, amplifying the signal. This allows the transistor to be used as an amplifier.

The 2N6228 is also used in feedback circuits to maintain a constant output level. This is known as negative feedback, where the output level is compared with the input level and an error signal is created. This error signal is then used to adjust the base current to adjust the output level to match the input level, providing a constantly regulated output level.

The 2N6228 has many advantages, such as its small size, low power output and its ability to be used in both switch and amplifier applications. This makes it an ideal choice for many low power applications.
