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.
So the value if R B will be.
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.
But this calculation will lead to the closest value to start with. TL — Programmable Reference Voltage. Engineering Program is accredited by: 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. 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.
2N2905 PNP Switching Transistor
To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA by using datadheet transistor to the base pin. Overall it is just another small signal transistor which is commonly used in switching and amplifying circuits. Submitted by admin on 21 June Here lets us assume the load here consumes around mA maximum so our collector current I C mA. Search the directory for faculty or staff members.
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 figure below. But it comes in a metal can package and can operate on voltages slightly higher than what a 2N can handle.
Soldering Tips Helpful Link: Complete Technical Details can be found at the datasheet given at dwtasheet end of this page.
However this vale will not be very accurate because the transistor will 2n290 an internal voltage drop across the collector current, so it mostly experimental to get the maximum current from the transistor. To make this current flow through the transistor the value of base current I B can be calculated using the below formula: You can also see open positions in the department.
The 2N is a NPN transistor and is normally used as a switch in many circuits.

Welcome to the ECE Store. So to calculate the resistor value of the base we can use the formulae. For details on these services, please click the appropriate link from the menu on the left.
Current flows in through collector, normally connected to 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. 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.
Amplifier modules like Audio amplifiers, signal Amplifier etc. 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 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. Datasheet if you looking for an NPN transistor that could switch loads or for decent amplification then 2N might the right choice for your project.
When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Spring Semester, Monday — Friday: Prices are subject to 2j2905 without notice.
