Here is an image showing the pin diagram of this transistor.The BC107B transistor can have a current gain of 200 to 450. The gain of the BC107 will be in the range from 110 to 450, for the BC107A it will be in the range from 110 to 220.The complementary PNP transistor to the BC107B is the BC177B.The 2SC1623 (SOT-23), 2SD601A (SOT-23), BC847 (SOT-23), BC847B (SOT-23), BC847BW (SOT-323), BC847W (SOT-323), BC850 (SOT-23), BC850B (SOT-23), BC850BW (SOT-323), BC850W (SOT-323), KSC1623 (SOT-23) and MMBT5210 (SOT-23) is the SMD version of the BC107B transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
