Overall it is just another small signal transistor which is commonly used in switching and amplifying circuits. Facilities Datasjeet Research in the department is conducted in a variety of laboratories equipped with state-of-the-art equipment, with research datasheft coming from federal, state, and private sources. 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.

Here lets us assume the load here consumes around mA maximum so our collector current I C mA. You can also see open positions in the department. To see a list of open positions, click here.

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 datasheeg below. Welcome to the ECE Store.

But this calculation will lead to the closest value to start with. Prices are subject to change without notice. Current Drains out through emitter, normally connected to ground.

Open Positions To see dwtasheet list of open positions, click here. Submitted by admin on 21 June To make this current flow through the transistor the value of base current I B can be calculated using the below formula:.

Another important thing to keep in mind, while using a transistor as switch is the base resistor. Engineering Program is accredited by: The 2N is a NPN transistor and is normally used as a switch in many circuits. So to calculate the resistor value of the base we can use the formulae.

Datashwet the value if R B dwtasheet be. 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.

This resistor is connected to the base pin of the transistor to limit the current flowing through the base. This stage is called Saturation Region. 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.

As we know the transistor is datawheet current controlled device meaning, we have pass some current I B thorough the base of the transistor to turn it on. Current flows in through collector, normally connected to load.

Amplifier modules like Audio amplifiers, signal Amplifier etc. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. The value of this current can be calculated by the required amount of current that will be consumed by the datashedt.

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. 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.

TL — Programmable Reference Voltage. Where h FE, is the current gain of the transistor which in our case is Soldering Tips Helpful Link: In addition to supporting the various labs in the EL building, we also provide equipment and manual check-out and a datasehet range of electronic components for sale. But it comes in a metal can package and can operate on voltages slightly higher dataheet what a 2N can handle. In our case for a collector current of mA we have to pass a base current of 16mA.

Spring Semester, Monday — Friday: 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.

Welcome to the ECE Store

Search the directory for faculty or staff members. 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 datqsheet current from the transistor.

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. Datashet Technical Details can be found at the datasheet given at the end of this page.
