Npn Transistor Switching Circuit. Example of npn transistor as a switch. In this structure we can observe the three terminals of transistor circuit currents and voltage value representations.
This pn junction based device has many applications such as high current load interfacing relay interfacing and motors interfacing through microcontrollers. 2sc1601 is a power transistor used for amplification and switching purposes. This bipolar junction transistor belongs to the npn transistor family where electrons are the major charge carriers.
If the transistor base terminal is 0 low then fan turns off for delay and other you can set with help of arduino ide and arduino uno.
It comes with two junctions i e. The transistor in which one p type material is placed between two n type materials is known as npn transistor the npn transistor amplifies the weak signal enter into the base and produces strong amplify signals at the collector end. When there is no voltage on base terminal it works as an open switch between collector and emitter. Npn transistor switching circuit diagram.
