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 I B can be calculated using the below formula:.

Prices are subject to change without notice. But this calculation will lead to the closest value to start with. 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.

However this vale will not be very accurate because the transistor will have an internal voltage drop across the collector current, so it mostly experimental to get the maximum current from the transistor. Spring Semester, Monday — Friday: So the value if R B will be. Where Vcc is the voltage on 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.

So if you looking for an NPN transistor that could switch loads or for decent amplification then 2N might the right choice for your project.

Welcome to the ECE Store

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. This stage is called Saturation Region. Engineering Program is accredited by: You can also see open positions in the department.


Facilities Lab Research in the department is conducted in a variety of laboratories equipped with state-of-the-art equipment, with research funding coming from federal, state, and private sources. So to calculate the resistor value of the base we can use the formulae. But it comes in a metal can package and can operate on voltages slightly higher than what a 2N can handle.

To see a list of open positions, click here. This resistor is connected to the base pin of the transistor to limit the current flowing through the base. Current Drains out through emitter, normally connected to ground.

In addition to supporting the various labs in the EL building, we also provide equipment and manual check-out and a wide range of electronic components for sale.

Overall it is just another small signal transistor which is commonly used in switching and amplifying circuits.

Open Positions To see a list of open positions, click here. Current flows in through collector, normally connected to load. Since transistor is of 2m2905 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.

Soldering Tips Helpful Datashedt For details on these services, please click the appropriate link from the menu on the left. To bias datashee 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.


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.

Where h FE, is the current gain of the transistor which in our case is Welcome to the ECE Store. The 2N is a NPN transistor and is normally used as a switch in many circuits. To make this current flow through the transistor the value of base current I B can be calculated using the below formula: Our People Search the directory for faculty or staff members.

Amplifier modules like Audio amplifiers, signal Amplifier etc. TL — Programmable Reference Dztasheet. Search the directory for faculty or staff members.

Another important thing to keep in mind, while using a transistor as switch is the base resistor. In our case for a collector current of mA we have to pass a base current of 16mA. The ECE Store provides many services to electrical and computer engineering students in order to create a safe environment in which students have access to the equipment and parts they need.


Complete Technical Details can be found at the datasheet given at the end of this page. Submitted by admin on 21 June When this transistor is fully biased then it can allow a maximum of mA to 2n2095 across the collector and emitter. Here lets us assume the load here consumes around mA maximum so our collector current I C mA.
