Additional Details

The 2SC2840 features a collector-emitter voltage (VCEO) rating suitable for many common power amplifier designs. Its high transition frequency allows it to operate effectively in VHF and UHF bands. The transistor is typically packaged in a small signal package for easy integration into circuit boards. The specific DC current gain (hFE) will vary depending on the operating conditions, but it is generally designed to provide adequate gain for typical amplifier configurations. Proper heat sinking may be required depending on the power dissipation levels in the application.
