What is a transistor and its function? A transistor is a semi-conductive electrical device. It is most often used as a microscopic on-off switch within an electrical circuit, or used to amplify a signal. What is a transistor used for? Transistors are used within electronic circuits as micros...
Switch Capabilities: An NPN transistor can act as a switch, with the ability to turn on in saturation mode and off in cut-off mode. What is a NPN Transistor An NPN transistor is the most commonly used bipolar junction transistor, and is constructed by sandwiching a P-type semiconductor bet...
The majority current—electrons in the npn transistor and holes in the pnp transistor—“arrives” in the collector region as Ic. The efficiency of charge transport from emitter to collector is given by the factor α, such that (4.7)Ic=αIe Fig. 4.7a shows a circuit to measure the collect...
Determine the pins: The 2N3904 transistor has three pins: the emitter (E), base (B), and collector (C) (C). Typically, the emitter is linked to earth, while the collector is connected to the load (such as an LED or a speaker). Determine the operating conditions: The transistor's op...
• Insert a noise filter for the output and communication line connected to the unit. NEC TOKIN Model ESD-SR-250 or equivalent is recommended.• The actual installation environments such as panel con-figurations, connected devices, connected wires, may af-fect the protection level of this ...

and can be produced on a massive scale, as is the case for things like transistors, there are some oddities that come up as a result of the process of making so many.This video goes into some of the intricacies of a bipolar junction transistor(BJT) and why it looks the way it does....
As shown in Fig. (2) the sensor responds to a physical phenomenon. If the sensor is inactive (nothing detected) then the active line is low and the transistor is off, this is like an openswitch. That means the NPN output will have no current in/out. ...
