Vukazahn This resistor is connected to the base pin of datssheet transistor to limit the current flowing through the base. But this calculation will lead to the closest value to start with. So the value if R B will be. To make this current flow through the transistor the value of base current I B can be calculated using the below formula:. Current flows in through collector, normally connected to load.

Jugor 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. In our case for a collector current of mA we have to pass a base current of 16mA.

But it comes in a metal can package and can operate on voltages slightly higher than what a 2N can handle. This stage is called Saturation Region. This resistor is datqsheet to the base pin of the transistor to limit the current flowing through the base. The 2N is a NPN transistor and is normally used as a switch in many circuits. Amplifier modules like Audio amplifiers, signal Amplifier etc. Here lets us assume the load here consumes around mA maximum so our collector current I C mA.

Where Vcc is the voltage datqsheet which the load operates and V BE is the voltage across the Base and Emitter which in our case according to the data sheet 1. However this vale will not be very accurate because the datashedt will have an internal voltage drop across the collector current, so it mostly experimental to get the maximum current from the transistor.

Complete Technical Details n be found at the datasheet given at the end of this page. Submitted by admin on 21 June 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. The value of this current can be calculated by the required amount of current that will be consumed by the load.

To make this current flow through the transistor the value of base current Trannsistor B can be calculated using the below formula:. Overall it is just another small signal transistor which is commonly used in switching and amplifying circuits. So datqsheet you looking for an NPN transistor that could switch loads or for decent amplification then 2N might the right choice for your project. Current Drains out through emitter, normally connected to ground. To make this current flow through the transistor the value of base current I B can be calculated using the below formula: TL — Programmable Transisgor Voltage.

As we know the transistor is a current controlled device meaning, we have pass some current I B thorough the base of the transistor to turn it on. Another important thing to keep in mind, while using a transistor as switch is the base resistor.

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA by using a transistor to the base pin. Where h FE, is the current gain of the transistor which in our case is Since transistor is of NPN the load to be switched should be connected to the collector and the emitter should be connected to the ground as show in the figure below.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. But this calculation will lead to the closest value to start with. TOP Related.

It is used in a variety of analog amplification and switching applications. PNA and other "Plastic" versions[ edit ] Replacements for the 2N are commonly available now in the cheaper TO packaging, where it is known as the PN or P2N, which has similar specifications except for the lower maximum collector current. Surface-mount versions[ edit ] Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. Similar types[ edit ] The BC family, including the BCA to BCC, are lower voltage, lower current, general-purpose transistors in TO packages, originating in Europe, that are often found in small-signal amplification and switching circuits of the type where the 2N might otherwise be used. They are not true replacements, but comparable devices that may be substituted only in circuits where the maximum current and voltage ratings are not exceeded. The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced Ic, e.
