2N5771 is a single bipolar junction transistor widely used in a variety of modules and circuits. It is classified into one of three types of transistors: Bipolar (BJT), Gate and Field-effect transistor (FET). This article will explain the applications field and working principle of 2N5771.

1. Applications field of 2N5771
   

   2N5771 has multiple applications in designing circuit and modules such as digital amplifiers, low voltage power supplies, switching circuits, and audio amplifiers. This particular 3-terminal device is also used in analogue-to-digital (A/D) and digital-to-analogue (D/A) converters. It can be used in a variety of battery operated equipment such as cell phones, portable radios, and car kits.

   Some medical equipment, including medical imaging scanners, also uses 2N5771 transistors. It helps in efficient integration of several control circuits in a single unit. It is also used in computers and peripherals for better integration and energy efficiency.

2. Working principle
   

   2N5771 consists of two PN junctions connected back-to-back between two terminals, hence forming a BJT. The two junctions are known as an emitter and a collector, with a third terminal called the base. The base-emitter junction is forward biased while the base-collector junction is reverse biased.

   When a small current passes through the BJT, the current flowing into the base will control the amplified current passing through the emitter-collector path. When the base terminal is forward biased, a current is able to enter it and flow out of the emitter junction. This increases the number of carriers in the collector junction and causes an amplified current to flow from collector to emitter.

2N5771 is a highly preferred BJT due to its low cost and high efficiency. It is highly reliable, making it suitable for many applications. Moreover, it has a low power consumption and its operation is relatively simple. It is not affected by electromagnetic interference thanks to its hermetic sealing.

In conclusion, 2N5771 is a single bipolar junction transistor with a wide range of applications. It consists of two PN junctions with one being forward biased while the other is reverse biased. This helps control the flow of current through the BJT, enabling it to amplify current. 2N5771 is inexpensive and efficient, making it an ideal choice for various circuits and modules.
