Product Overview
The 2SC4793 is an NPN bipolar power transistor designed for high-voltage amplification, driver, and switching applications. It features a 230V collector-emitter voltage rating, 1A maximum collector current, and 50W power dissipation. Its combination of high voltage capability and moderate current handling makes it suitable for discrete power amplifier, linear control, and high-voltage driver stages.
Packaged in a TO-220F-3 fully insulated through-hole package, the 2SC4793 is suitable for heatsink-mounted designs requiring electrical isolation and reliable thermal handling. Its 40MHz transition frequency also supports audio-frequency and other medium-speed power amplification applications.
