The introduction
of the Transistor Type NPN and PNP
A Transistor is a
semiconductor device that is used as a reinforcement, cutters (switching),
voltage stabilization, signal modulation or other functions. Transistor is
essentially active components with current, voltage or power output was
controlled by the input current. In the communication system of the transistor
is used as a signal amplifier. In the electronic transistor computer strands
used for high speed electronic switch.
The Transistor is
a very important component in the world of modern electronics. In analog
circuits, transistors used in amplifiers (boosters). Analog circuits include
loudspeakers, power source is stable, and the radio repeater. In series-a
series of digital, the transistor is used as a high-speed switch. Some
transistor can also be strung together in a way that serves as a logic gate,
memory, and other components.
Transistor
Structure
The Transistor is
the electronics components multytermal, has 3 terminals, base, collector, emitter.
Literally, the word ' Transfer ' means ' Transistor resistor ', which is a
component of the value of the resistance between its terminal can be set up.
There are two
types of transistor NPN and PNP looks like the picture below:
Connections
(junction) transistor NPN and PNP is seen in the picture below:
NPN PNP
Transistor and have properties that are opposite to each other, although in
fact both types of transistor the working principle is the same. Transistor for
PNP in need current and voltage with NPN transistor opposing. If in an NPN
transistor collector more positive than on the emitter, the PNP transistor
emitter more positive from the foot of the collector.
