Under no interference there will be a positive voltage appearing at the base of the PNP transistor and based on working on PNP transistor having a positive voltage at gate leaves transistor in high resistance state.

Soldering Tips Helpful Link: The higher-power 2N is a very similar NPN transistor that can safely switch three times as much current as the 2N As shown in below graph a current of 10mA needs to flow out of base for a flow of mA collector current and switching ON the transistor completely.

To see a list of open positions, click datasheef. And so when the button pressed current flows though the motor turning it ON. The complementary PNP transistor is 2N The 2N is used very frequently in hobby electronics projects, including home-made ham radioscode-practice oscillators and as an interfacing device for microcontrollers.

From Wikipedia, the free encyclopedia. With this current flow the transistor gets turned ON and a current flows through the collector followed by motor.

It is designed for low current and powermedium voltageand can operate at moderately high speeds. You can also see open positions in the department. In other projects Wikimedia Commons.

Working Under no interference there will be a positive voltage appearing at the base of the PNP transistor and based on working on PNP transistor having a positive voltage at gate leaves transistor in high resistance state.

The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. So when a positive voltage appears at base only leakage current flows through transistor and all the battery voltage BAT1 appears across it. How to use 2N Transistor 2N can be used in any general transistor application circuits but for understanding the working let us consider a simple 2N switching circuit as shown below.

When the button is pressed the base of the transistor will be connected to the ground and a loop will be formed for the current to flow from the base to the ground.

Submitted by admin on 31 October For details on these services, please click the appropriate link from the menu datashet the left. 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 small button here is for providing the trigger to the transistor and can be removed to leave simple contacts to touch.

Dstasheet Commons has media related to 2N This page was last edited on 18 Octoberat Retrieved datashret ” https: Based on the characteristic of a PNP transistor the current needs to flow out of base not in to the base for it to turn ON. Archived from the original on Engineering Program is accredited by: In the above circuit we are using 2N as a simple switching device and a small motor as the load.

After the button opened again the base current flow will be cutoff there by turning OFF the motor. Hence we datassheet used 2N as a simple switching device and in the same way we can use this transistor in all other application circuits.
