Here is an image showing the pin diagram of this transistor.The 2SA794 transistor can have a current gain of 90 to 220. The gain of the 2SA794-Q will be in the range from 90 to 155, for the 2SA794-R it will be in the range from 130 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SA794 might only be marked "A794".The complementary NPN transistor to the 2SA794 is the 2SC1567.The 2SA1368 (SOT-89) is the SMD version of the 2SA794 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA794 with the 2SA1021, 2SA1184, 2SA1220, 2SA1220A, 2SA1358, 2SA794A, 2SA795, 2SA795A, 2SB1167, 2SB1168, 2SB549, 2SB631, 2SB631K, 2SB649, BD792, KSA1220, KSA1220A, KTA1700 or MJE254.
