What are the functions of the 2N2222 transistor?
The 2N2222 transistor is subdivided into one group according to its DC current gain. On special request, these transistors can be manufactured in different pin configurations. Functions : NPN General Purpose Amplifier / Switch requiring collector currents up to 500mA
What is the DC collector current of 2N2222?
It is made of silicon material and specially designed for low voltage, low to medium current and low power amplifier applications. 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.
What can a NPN planar transistor be used for?
NPN Silicon Epitaxial Planar Transistor for switching and AF amplifier applications. NPN silicon planar transistors in TO 18 case (18 A 3 DIN 41876). The collector is electrically connected to the case. The transistors are particularly suitable for use as high-speed switches.
How are Darlington pair transistors used in electronics?
Darlington pair transistors where more than one transistors are connected in parallel for obtaining the high current from emitter to collector. It could be used as an amplifier for amplifying current, voltage, and power. A 2D diagram helps while designing a PCB diagram and during electronics components assembly.
What’s the difference between BC547 and 2N2222A transistor?
The 2N2222A transistor is very much similar to the commonly used NPN transistor BC547. But there are two important features that distinguish both. 2N2222A can allow collector current upto 800mA and also has power dissipation of 652mW which can be used to drive larger loads than compared with BC547.
What are the features of the 2N2222A pinout?
2N2222A Pinout Configuration Pin Number Pin Name Description 1 Emitter Current Drains out through emitter 2 Base Controls the biasing of transistor 3 Collector Current flows in through collector
