2N3905 Datasheet, Equivalent, Cross Reference Search

Spring Semester, Monday — Friday: This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists. When the button is pressed the base 23905 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. The 2N is used very frequently in hobby electronics projects, including home-made ham radioscode-practice oscillators and as an interfacing device for microcontrollers.

In the above circuit we are using 2N as a simple switching device and a small motor as the load.

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.

The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. And so when the button pressed current flows though the motor turning it ON.

Wikimedia Commons has media related to 2N The component is cheap and easy to dztasheet with so it is best suited when choosing a random switching device. Soldering Tips Helpful Link: Submitted by admin on 31 October In other projects Wikimedia Commons.

The complementary PNP transistor is 2N It is designed for low current and powermedium voltageand can operate at moderately high speeds. After the dataeheet opened again the base current flow will be cutoff there by turning OFF the motor. Archived from the original on Welcome to the ECE Store.

This page was last edited on 18 Octoberat 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. Retrieved from ” https: With the gain of the transistor a simple touch can trigger it. Our People Search the directory for faculty or staff members.

The higher-power 2N is a very similar NPN transistor that can safely switch three times as much current as the 2N With this current flow the transistor gets turned ON and a current flows through the collector followed by motor. So when a positive voltage appears at base only leakage current flows through transistor and all the battery voltage BAT1 appears across it.

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.
