Current flows in through collector, normally connected to load. So if you looking for an NPN transistor that could switch loads or for decent amplification then 2N might the right catasheet for your project. 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.

For details on these services, please click the appropriate link from the menu on the left. Where h FE, is the current gain of the transistor which in our case is To see a list of open positions, click here. 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. Complete Technical Details can be found at the datasheet given at the end of this page. Spring Semester, Monday datasjeet Friday: To make this current flow through the transistor the value of base current I B can be calculated using the below formula: TL — Programmable Reference Voltage.

Current Drains out through emitter, normally connected to ground. This stage is called Saturation Region.

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 2n295 below. To make this current flow through the transistor the value of base current I B can be calculated using the below formula:. In our case for a collector current of mA we have to pass a base current of 16mA.


Soldering Tips Helpful Link: 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. The value of this current can be calculated by the required amount of current that will be consumed by the load. 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.

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.

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.

But it comes in a metal can package and can operate on voltages slightly higher than what a 2N can handle. Search the directory for faculty or staff members. Open Positions To see a list of open positions, click here.

PNP, Met, 60V 500mA, GP Amp & Sw – 2N2905

Welcome to the ECE Store. Overall it is just n22905 small signal transistor which is commonly used in switching and amplifying circuits. But this calculation will lead to the closest value to start with. The 2N is a NPN transistor and is normally used as a switch in many circuits.


Another important thing to keep in mind, while using a transistor as switch is the base resistor. This resistor is connected to the base pin of the datashedt to limit the current flowing through the base. So the value if R B will be. 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. So to calculate the resistor value of the base we can use the formulae.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Amplifier modules like Audio amplifiers, signal Amplifier etc. Submitted by admin on 21 June Prices are subject to change without notice. Here lets us assume the load here consumes around mA maximum so our collector current I C mA. Engineering Program is accredited by: You can also see datashet positions in the department.

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. 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.
