2SC5200 NPN Transistor – Datasheet

Introduction

The 2SC5200 is a highly popular NPN power transistor widely utilized in high-power audio circuits and audio frequency amplifiers. Its status as a power transistor stems from its impressive electrical characteristics, which include a high collector-emitter breakdown voltage of 230V, a substantial collector current of 15A, and a high current gain (hFE​) of up to 160. These robust specifications make it ideal for applications requiring significant power handling and amplification.

The 2SC5200 is often paired with its complementary PNP counterpart, the 2SA1943 transistor. These two transistors are frequently used together in a push-pull configuration in audio amplifier designs. In this setup, the NPN and PNP transistors work in tandem to amplify both the positive and negative halves of an AC signal, resulting in a more efficient and higher-fidelity output. This complementary pairing is a hallmark of many classic audio amplifier circuits.

Originally manufactured by Toshiba, the 2SC5200 has largely been succeeded by more cost-effective alternatives, such as the TTC5200. While the original Toshiba part may be considered obsolete, many other manufacturers continue to produce 2SC5200 equivalents due to its enduring popularity and widespread use in existing designs. Its legacy in the world of audio electronics solidifies its place as a cornerstone component for hobbyists and professionals alike.

Key Applications of the 2SC5200

The 2SC5200 transistor is a cornerstone component in high-fidelity audio electronics, particularly in stereo amplifier circuits with power ratings of 200W or more. Its exceptional performance in audio applications is due to a wide frequency response ranging from 5Hz to 100kHz. This broad range ensures it can accurately reproduce the full spectrum of audible sound. Paired with a high input sensitivity of just 0.75Vrms and minimal total harmonic distortion (THD), the 2SC5200 is an ideal choice for audio power amplifier designs that demand both clarity and power.

• Audio frequency amplifiers: The transistor’s main application is in high-power audio circuits and amplifiers.

• Push-pull configurations: It’s frequently used with its complementary transistor, the 2SA1943, to create robust amplifier stages.

• Switching applications: The 2SC5200 is also a reliable high-current switching element. This makes it suitable for use in:
  • Switch-mode power supplies (SMPS)
  • Driving relays
  • Power inverters and converters (DC to AC converters)

• Power control circuits: Its ability to handle high power and switch efficiently makes it useful for various power control and supply systems.
