Spring Semester, Monday — Friday: 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.

But it comes in a metal can package and can operate on voltages slightly higher than what a 2N can handle. 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. This resistor is connected to the base pin of the transistor to limit the current flowing through the base.

Where h FE, is the current gain of the transistor which in our case is 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.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Overall it is just another small signal transistor which is commonly used in switching and amplifying circuits. This stage is called Saturation Region.

You can also see open positions in the department. Open Positions To see a list of open positions, click here. In our case for a collector current of mA we have to pass a base current of 16mA.

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. 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.

To make this current flow through the transistor the value of base current I B can be calculated using the below formula: The value of this current can be calculated by the required amount of current that will be consumed by the load.

The ECE Store provides many services to electrical and 2n2950 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.

Current Drains out through emitter, normally connected to ground. Prices are subject to change without notice.

But this calculation will lead to the closest value to start with. 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.

Here lets us assume the load here consumes around mA maximum so our collector current I C datashedt. 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 to calculate the resistor value of the base we can use the formulae. Amplifier modules like Audio amplifiers, signal Amplifier etc.

TL — Programmable Reference Voltage. Current flows in through collector, normally connected to load. So the value if R B will be.
