2SA0794 (2SA794), 2SA0794A (2SA794A) are silicon PNP epitaxial planar type transistors from Toshiba. They are suitable for low-frequency output driver circuits. The devices have high collector-emitter open circuit voltage (VCEO), which makes them suitable for low-frequency 40W to 100W output power amplifier driver stages. 2SA0794A has a VCEO of -120V, which is 20V higher than that of 2SA0794. 2SA0794, 2SA0794A are packaged in TO-126B, which does not require an insulation plate to be installed on the heat sink.
