2SC4793 Specs and Replacement
The 2SC4793 is an NPN bipolar junction transistor designed for high-voltage, high-speed power applications. Built with an epitaxial silicon structure, it offers a collector-emitter voltage rating of up to 230V and a collector current of 1A, making it suitable for audio amplifier driver stages, switching regulators, power supplies. Its relatively low saturation voltage improves efficiency, while the high transition frequency (typically around 100 MHz) supports fast switching and wide-bandwidth operation. The device also features good thermal stability thanks to its TO220F or similar fully insulated package, allowing efficient heat dissipation under continuous load. The 2SC4793 is valued for its reliability, speed, robust electrical performance in demanding analog and switching designs.
