Here is an image showing the pin diagram of this transistor.The 2SB502A transistor can have a current gain of 30 to 280. The gain of the 2SB502A-O will be in the range from 50 to 140, for the 2SB502A-R it will be in the range from 30 to 70, for the 2SB502A-Y it will be in the range from 100 to 280.Sometimes the "2S" prefix is not marked on the package - the 2SB502A might only be marked "B502A".The complementary NPN transistor to the 2SB502A is the 2SD877.
