Introduction:
As one of the key semiconductor devices, the transistor has found the use of electronic applications such as embedded systems, digital circuits, and control systems. In both digital and analog domains transistors are widely used for different application applications such as amplification, logic operation, switching and so on. Bipolar Junction Transistor or BJT three-layer, three terminal and two semiconductor devices. In most applications these transistors are used for two basic functions such as switching and used for amplification.
Core Parameters:
· Collector to emitter Voltage – 600V
· DC current gain - 75
· Current of the collector – 20A
· Insulated type

Working:
We all know that the transistor has 4 operating circuits, where Active, Cutoff and Saturation are often used. The transistor operates in the active region when used as an Amplifier. Where the transistor operates as a Switch it operates at cut-off and in saturation region. At Cutoff region both the Emitter Base Junction and Collector Base junction are in opposite direction. But in the saturation region both junctions are in the same direction. Bi-polar means two type of charge carriers are present in the working situation of BJT.

Applications:
· Air-conditioners
· Converters (small to medium size)
· CVCF

I recently purchased the integrated circuit QM20TD-H304 from Utsource and I am very pleased with the quality of the product. The circuit was easy to install and worked perfectly right out of the box. The documentation was also very helpful and made it easy to understand the product. I would highly recommend Utsource to anyone looking for quality integrated circuits.
