2SC5200 Transistor configuration, applications & working principle
The 2SC5200 transistor is a NPN polarity based power transistor, designed for use in general purpose switching and power amplifier based applications. This transistor has three terminals and three layers where the terminals are the emitter, base and collector and the layers are N and P&N. Here, the doped layer is arranged between two doped layers. Therefore, this article is about an overview of the 2SC5200 transistor which includes its working and applications.
What is 2SC5200 transistor?
2SC5200 is an NPN transistor, used in various AF amplifiers and high power audio circuits due to its high collector current and high current gain. This transistor is manufactured by Toshiba and is still being replaced by the TTA5200.
This high-power transistor can be accessed in the TO-264 package made of epoxy and plastic to design different amplifiers. The collector emitter voltage (VCE) of this transistor is 230V while the collector current is 30A. These transistors are used in televisions, mobile phones, flip-flops, industrial control, etc.
2SC5200 NPN Transistor
Once these transistors operate with a high collector current and switching frequency, they heat up very quickly, and therefore they are always used with a heat sink. So that the circuit can be protected from overheating.
In most amplifier circuit designs, a 2SC5200 transistor is used in conjunction with its complement such as the 2SA1943. Similar to Class B amplifiers, most amplifiers use a push-pull circuit that includes two transistors such as PNP and NPN. Therefore both transistors are frequently used together to build high power amplifiers.
