Here is an image showing the pin diagram of this transistor.The 2SB1202 transistor can have a current gain of 100 to 560. The gain of the 2SB1202-R will be in the range from 100 to 200, for the 2SB1202-S it will be in the range from 140 to 280, for the 2SB1202-T it will be in the range from 200 to 400, for the 2SB1202-U it will be in the range from 280 to 560.Sometimes the "2S" prefix is not marked on the package - the 2SB1202 might only be marked "B1202".The complementary NPN transistor to the 2SB1202 is the 2SD1802.The 2SB1123 (SOT-89) and 2SB1124 (SOT-89) is the SMD version of the 2SB1202 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
