The SS8050B is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, base, and collector leads.
Here is an image showing the pin diagram of this transistor.The SS8050B transistor can have a current gain of 85 to 160. The gain of the SS8050 will be in the range from 85 to 300, for the SS8050C it will be in the range from 120 to 200, for the SS8050D it will be in the range from 160 to 300.The complementary PNP transistor to the SS8050B is the SS8550B.The MPS8050S (SOT-23) and MPS8050S-B (SOT-23) is the SMD version of the SS8050B transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the SS8050B with the MPS650, MPS650G, MPS8050 or MPS8050B.
