The PN100 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 complementary PNP transistor to the PN100 is the PN200.The MMBT100 (SOT-23) is the SMD version of the PN100 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the PN100 with the KSP05, KSP06, MPS651, MPS651G, MPSA05, MPSA05G, MPSA06, MPSA06G, MPSW05, MPSW05G, MPSW06 or MPSW06G.
