Spring Semester, Monday — Friday: This page was last edited on 18 Octoberat Engineering Program is accredited by: The higher-power 2N is a very similar NPN transistor that can safely switch three times as much current as the 2N Circuitbuilding do-it-yourself for Dummies.

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.

As shown in below graph a current of 10mA needs to flow out of base for a flow 2n39905 mA collector current and switching ON the transistor completely.

After the button opened again the base current flow will be cutoff there by turning OFF the motor. 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.

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

Our People Search the directory for faculty or staff members. The small button here is for providing the trigger to the transistor and can be removed to leave simple contacts to touch. Commons category link is on Wikidata. Search the directory for faculty or staff members.

With this current flow the transistor gets turned ON and a current flows through the collector followed by motor. This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists.

Welcome to the ECE Store

The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. 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.

So when a positive voltage appears at base only leakage current flows through transistor and all the battery voltage BAT1 appears across it.

TL — Programmable Reference Voltage. 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. 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.

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. Retrieved from ” https: The complementary PNP transistor is 2N With the gain of the transistor a simple touch can trigger it.

The component is cheap and easy to work with so datassheet is best suited when choosing a random switching device. Prices are subject to change without notice. Views Read Edit View history.

It is used in a variety of analog amplification and switching applications. Hence we have used 2N as a simple switching device and in the same way we can use this transistor in all other application circuits. Submitted by admin on 31 October It is designed for low current and powermedium voltagedataheet can operate at moderately high speeds.

In the above circuit we are using 2N as a simple switching device and a small motor as the load. Welcome to the ECE Store. You can also see open positions in the department.
