Brief Description on 2N Transistor 2N is a NPN transistor hence the collector and emitter will be left open Reverse biased when the base pin is held at ground and will be closed Forward biased when a signal is provided to base pin. The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. To bias a transistor we have to supply current to base pin, this current IB should be limited to 5mA. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. But there are two important features that differentiate the 2N and 2N

A complete step by step tutorial on the Introduction to 2n You are here: Electronic Components Introduction to 2n Hey Everyone! I hope you are doing great and having fun with your lives.

I am back to give you a daily dose of information so you can grow and progress in your relevant field. Today, I am going to uncover the details on the Introduction to 2n It is an NPN negative-positive-negative bipolar junction transistor BJT which is used for general purpose amplification and switching purpose. It consists of P doped semiconductor that exists between the two layers of N doped material. Introduction to 2n 2n is an NPN bipolar junction transistor which is used for general purpose amplification and switching purpose.

It is called bipolar junction transistor because conduction is carried out by both charge carriers i. It mainly consists of three terminals called emitter, base, and collector. Small current present at the base side is used to control the large current at the emitter and conductor side.

P layer of this transistor represents the base terminals while other two N layers represent emitter and collector respectively. Base is positive with respect to emitter. When a positive voltage is applied at the base side, it gets biased and allows the current to flow from emitter to collector.

The emitter emits the electrons which are then collected by the collector and base controls the number of electrons. A transistor is a combination of diodes joined back to back.

When small current controls the large current at the emitter and collector, this process is used for amplification purpose. Circuit Diagram of 2n Circuit diagram of 2n is shown in the figure below. The voltage at the collector side is more than the voltage at the base side.

This transistor comes with three main configurations i. Common emitter configuration is mainly used for amplification purpose because it exhibits the required voltage and power gain for amplification purpose.

This configuration helps in increasing the input signal by 20dB which is nearly times more than the input signal. Emitter current is the combination of base and collector current. Collector and emitter can be differentiated by their size and doping concentration. The emitter is highly doped while the collector is lightly doped.

This beta is actually an amplification factor which is a measure of current being amplified. Beta value ranges between 20 to but its standard value is Beta is a ratio of two current so it has no unit. Alpha value ranges between 0. Absolute Maximum Ratings of 2n Absolute maximum ratings of 2n is shown in the figure below. Collector-Emitter and Collector-Base voltages are 40 and 60 V respectively. If stresses are exceeded above these absolute maximum ratings, they can damage the device.

Similarly, if stresses are applied for the extended period of time, they can affect the device reliability. Electrons are majority charge carriers in case of NPN transistor while holes are majority charge carriers in case of PNP transistors.

Most of the professional prefer NPN transistor over PNP transistor because conduction carried out by the mobility of electrons is better than conduction through mobility of holes. Applications This transistor is mainly used for general purpose amplification.

In many applications, this transistor behaves as a simple switch. When a voltage is applied at the base side, it gets biased and transistor behaves as an ON switch. I hope you have enjoyed the article.
