Here is an image showing the pin diagram of this transistor.The 2SA794A transistor can have a current gain of 90 to 220. The gain of the 2SA794A-Q will be in the range from 90 to 155, for the 2SA794A-R it will be in the range from 130 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SA794A might only be marked "A794A".The complementary NPN transistor to the 2SA794A is the 2SC1567A.You can replace the 2SA794A with the 2SA1021, 2SA1184, 2SA1220, 2SA1220A, 2SA1358, 2SA795, 2SA795A, 2SB631K, 2SB649, KSA1220, KSA1220A or KTA1700.
