semiconductor device, the 2N2222A, is used to amplify or switch electronic
signals and electrical power. It's made of semiconductor material and has at
least three terminals for connecting to a circuit outside of it. The current
through another pair of terminals is controlled by a voltage or c..
The 2N3904 is
a common NPN bipolar junction transistor used for general-purpose
low-power amplifying or switching applications. ... It is a 200 mA, 40 V, 625
mW transistor with a transition frequency of 300 MHz, with a minimal
beta, or current gain, of 100 at a collector..
an NPN bi-polar junction transistor. A transistor, stands for
transfer of resistance, is commonly used to amplify current. A small current at
its base controls a larger current at collector & emitter terminals. Its equivalent transistors are BC548
general purpose silicon, NPN, bipolar junction transistor. It is used for
amplification and switching purposes. The current gain may vary between 110 and
800. BC548 is used in common emitter configuration for amplifiers.
a general purpose PNP transistor. It is used in switching and amplifier
applications. The DC current gain varies in range 110 to 800. BC558 is
