The 2SC5200 transistor is an NPN polarity-based power transistor, designed to use in general-purpose switching and power amplifier-based applications. This transistor includes three terminals and three layers where terminals are emitter, base & collector and layers are N, P & N. Here, the p doped layer is arranged between two n doped layers. So, this article discusses an overview of a 2SC5200 transistor which includes its working & its applications.

What is 2SC5200 Transistor?

The 2SC5200 is an NPN transistor, used in different AF amplifiers and high power-based audio circuits because of its high collector current and high gain of current. This transistor is manufactured by Toshiba and it is still replaced with TTA5200.

This high-power transistor is accessible in the TO-264 package which is made with epoxy & plastic material for designing different amplifiers. The collector to emitter voltage (VCE) of this transistor is 230V whereas the collector current is 30A. These transistors are used in TVs, mobiles, flip flops, industrial control, etc.

Once these transistors operate through high collector current and switching frequency then they heat up very quickly, thus they are used with a heat sink always. So that the circuit can be protected from overheating.

In most of the amplifier circuit designs, 2SC5200 transistor is used along with its complement like 2SA1943. Similar to Class B amplifiers, most of the amplifiers use a push-pull circuit including two transistors like PNP & NPN. So both the transistors are used together frequently to build high-power-based amplifiers.
