For details on these services, please click the appropriate link from the menu on the left. The value of this current can be calculated by the required amount of current that will be consumed by the load. This resistor is connected to the base pin of the transistor to limit the current flowing through the 2n29055. To make this current flow through the transistor the value of base current I B can be calculated using the below datasheet.

You can also see open positions in the department.

Current Drains out through emitter, normally connected to ground. 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. Current flows in through collector, normally connected to load. Overall it is just another small signal transistor which is commonly used in switching and amplifying circuits. The 2N is a NPN transistor and is normally used as a switch in many dafasheet. But it comes in a dahasheet can package and can operate on voltages slightly higher than what a 2N can handle.

But this calculation will lead to the closest value to start with. Another important thing to keep in mind, while using a transistor as switch is the base resistor. Dataheet this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

Search the directory for faculty or staff members. Spring Semester, Monday — Friday: Here lets us assume the load here consumes around mA maximum so our collector current I C mA.

Engineering Program is accredited by: 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. Where h FE, is the current gain of the transistor which in our case is Complete Technical Details can be found at the datasheet given at the end of this page. 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: So to calculate the resistor value of the base we can use the formulae.

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. 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.

Our People Search the directory for faculty or staff members. This stage is called Saturation Region. Where Vcc is the voltage on which the load operates datssheet V BE is the voltage across the Base and Emitter which in our case according to 2n2950 data sheet 1. 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.

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.

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. Welcome to the ECE Store. TL — Programmable Reference Voltage.
