In which device 2N2222 transistor is used?
2N2222 NPN transistor has been commonly used for switching and very high frequency(VHF) amplifier applications. It is made of silicon material and specially designed for low voltage, low to medium current and low power amplifier applications.
What is the function of 2N2222 transistor?
The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds.
What is BC548 transistor?
The BC548 is a general-purpose NPN bipolar junction transistor commonly used in European and American electronic equipment. It is notably often the first type of bipolar transistor hobbyists encounter and is often featured in designs in hobby electronics magazines where a general-purpose transistor is required.
How does a driver circuit work?
Driver circuits. To control smaller devices that use DC, a transistor-based driver circuit can be used to boost the current to the levels needed for the device. When voltage and current levels are in the correct range, the transistor acts like a high-current switch controlled by the lower current digital logic signal.
What is meant by driver circuit?
In electronics, a driver is a circuit or component used to control another circuit or component, such as a high-power transistor, liquid crystal display (LCD), stepper motors, and numerous others. Typically the driver stage(s) of a circuit requires different characteristics to other circuit stages.
Is a transistor a circuit?
Transistor, semiconductor device for amplifying, controlling, and generating electrical signals. Transistors are the active components of integrated circuits, or “microchips,” which often contain billions of these minuscule devices etched into their shiny surfaces.
What can 2N2222 NPN transistor be used for?
1 This 2N2222 NPN Transistor could be used in that loads where current is required more than 800mA 2 It could be used in motor drive circuits such as variable frequency drives (VFD) etc. 3 It could be used in dc inverters and rectifier circuits.
What is the DC collector current of 2N2222?
2N2222 provides continuous dc collector current is 800mA. It means it has a high collector therefore it is mostly used in that circuits where low to medium current is required. It works on high transition frequency value 250MHz with delay time 10ns, rise time 25ms, storage time 225ms and fall time 60ms.
How is the base resistor on a 2N2222 relay connected?
Hi, the 2n2222 have a base resistor of 270ohms which is connected to a micro. The collector is connected to the relay and the emitter is connected to ground. What is the base current or voltage ahead of the base 270ohm.
Are there any alternatives to the 2N2222 IC?
Alternatives for the 2N2222 are now commonly available in TO-92 packaging e.g. P2N2222 which has alike specifications excluding lower max collector current Ic. However the pins order for P2N2222 is different from 2N2222. Actually the collector and emitter pins are interchanged.
