The C5200 is a high-performance NPN transistor designed primarily for audio power amplifier output stages. Manufactured using BiT-LA technology, it offers excellent gain linearity and high transition frequency, making it ideal for clean audio reproduction.
With a collector-emitter voltage of 230V and collector current capacity of up to 15A (30A peak), the 2STC5200 handles heavy loads without compromising thermal stability or response speed. It comes in a TO-264 package, allowing for robust heatsink mounting and effective power dissipation.
This transistor is highly regarded in professional audio equipment and is often paired with the complementary 2STA1943 PNP transistor in Class AB push-pull amplifier designs. Its fast switching time also makes it suitable for high-speed power control circuits.
If you’re building a new amp, replacing output transistors, or working on a linear regulator, the C5200 is a proven performer. NOTE – This transistor comes in two variants – The 2STC5200 by STMicroelectronics and the 2SC5200 by Toshiba Corporation.
