C5200 transistor

The 2SC5200 (C5200) is a high-power NPN bipolar junction transistor designed specifically for audio amplifier output stages and high-fidelity applications. Renowned for its excellent linearity, high current capability, and wide safe operating area, it is a popular choice for DIY audio enthusiasts and professional amplifier designs. Often used in complementary pairs with its PNP counterpart, the 2SA1943.

✅ Specifications:
