The MPS8550C 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 MPS8550C transistor can have a current gain of 120 to 200. The gain of the MPS8550 will be in the range from 85 to 300, for the MPS8550B it will be in the range from 85 to 160, for the MPS8550D it will be in the range from 160 to 300.The complementary NPN transistor to the MPS8550C is the MPS8050C.The MMBT3702 (SOT-23), MPS8550S (SOT-23) and MPS8550S-C (SOT-23) is the SMD version of the MPS8550C transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MPS8550C with the MPS750, MPS750G, SS8550, SS8550C or ZTX949.
