TRANSISTOR
Transistors are semiconductor devices used as amplifiers, as the circuit breaker and connecting (switching), voltage stabilization, signal modulation, or as other functions. Transistor can act like an electric faucet, where according to input current (BJT) or voltage input (FET), which allows electrical conduction of the circuit is very accurate source of electricity.

Through-hole transistors (compared with measuring tape centimeters)
In general, the transistor has 3 terminals. Voltage or current terminal installed in a set larger currents through the other terminal 2. Transistor is a very important component in modern electronic world. In analog circuits, transistors used in amplifiers (boosters). Analogue circuit surrounding loudspeakers, stable electricity sources, and radio signal amplifier. In digital circuits, transistors used as high-speed switches. Some transistors can also be arranged in such a way that serves as a logic gate, memory and other components.

TYPES OF TRANSISTOR
In general, the transistor can be differentiated based on many categories:
Semiconductor materials: Germanium, Silicon, Gallium arsenide
Physical Packaging: Through Hole Metal, Plastic Through Hole, Surface Mount, IC, etc.
Type: UJT, BJT, JFET, IGFET (MOSFET), IGBT, HBT, MISFET, VMOSFET, MESFET, HEMT, SCR and the development of the transistor that is IC (Integrated Circuit) and others.
Polarity: NPN or N-channel, PNP or P-channel
Maximum power capacity: Low Power, Medium Power, High Power
Maximum working frequency: Low, Medium, or High Frequency, RF transistors, Microwave, etc.
Applications: Amplifier, Switch, General Purpose, Audio, High Voltage, etc.
