Emitter current is the sum of base and collector current.Current will sink into the base side in case of PNP transistor while current from the base side will source to the transistor in case of NPN transistor. The NPN and PNP transistor encompass same features with some exceptions i.e.This transistor is a current controlled device where a small amount of current at the base side is used to handle a large amount of current at the emitter and collector side.As it is an NPN silicon transistor so it has positive base terminal and a negative emitter terminal.The circuit symbol of 2n3055 is shown in the figure given below. Conduction is carried out when electrons emit from the emitter and are collected by the collector.A small amount of base current is used to control the large current at the emitter and base side.

Pinout of 2n3055 is given in the figure below. This transistor is a bipolar current controlled device which is different than JFET which is a unipolar voltage controlled device.Дўn3055 consists of three terminals which are given below.Mica insulator is added in the manufacturing process that isolates the case of the transistor from the heat sink.However, proper care should be given in order to mount the device perfectly, otherwise, it can harm the device at large.This device is manufactured in such a way it can function with an efficient heat sink.However, in most of the application when an ambient temperature is high, low power dissipation is expected.The 2n3055 is connected to a heat sink which widely effects the overall power dissipation by the transistor.The maximum collector-emitter voltage is highly dependent on the resistance intensity between emitter and base, provided by the external circuit.It is important to note that it wonвЂ™t be useful for amplification purpose when it is configured with common emitter configuration as it encompasses a transition frequency of around 3 MHz that will allow the forward current gain drop to 1.This NPN transistor can be configured with three configurations named as a common collector, common base, and common emitter configuration.It comes with lots of electronic applications but mostly it is used for switching and amplification purpose.P-doped layer of transistor acts like a base while other two N sides represent emitter and collector respectively.

As 2n3055 is an NPN transistor, here base with positive with respect to emitter and P layer lies between the two layers of N doped semiconductor.

The measure of base current to control the large current at the emitter and collector side is used for amplification purpose.

It is a bipolar device in which conduction is carried out by the movement of both charge carriers i.e electrons and holes.

Unlike FETs(Field effect transistors) it is a current controlled device in which small current at the base side is used to control a large amount of current at the emitter and collector side.

The 2n3055 is a semiconductor NPN bipolar transistor which consists of three terminals called emitter, base, and collector.

IвЂ™ll try to cover as many aspects possible related to this device so can get a brief overview about what it does and what are the applications it is used for. It is a semiconductor NPN (negative-positive-negative) power transistor which comes in TO-3 Casing. Today, I am going to unlock the details on the Introduction to 2n3055. I am back to feed your stomach with plenty of information so you can progress and grow in real life. If the capacitor value is increased, the high-frequency response will be even greater.Hey Guys! Hope you all are doing great and having fun with your lives. Whereas capacitor C3 used to produce a higher frequency (treble). If the value of the capacitor C2 is greater, the bass tone will be lower. However, if the potentiometer is set too low, the final amplifier transistor will not be too hot, but the output sound will be distorted.Д¬apacitor C2 used to adjust the low-frequency tone (bass). Potentiometer must be set to get the best sound possible without distorted.Д«ut if the current too high, it will be wasteful of power and the final amplifier transistor becomes very hot. But the current can be adjust with a potentiometer trimmer. This circuit is of the class B type amplifier, meaning that current will continue to flow through the transistor, even when there is no signal input. With a voltage of +55 VDC, the output power produced is around 60 Watts. The final amplifier transistor is arranged with Darlington to produce for high gain. You can see the component values вЂ‹вЂ‹of this circuit are very easy to find even at home. While the maximum signal input voltage is 1 Volt. But the advantages of this amplifier circuit can work with a voltage of 30-60 VDC. The optimal working voltage for this amplifier is +55 Volts.

This circuit is designed with a simple and low cost.
