The PN100A 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 PN100A is the PN200A.The MMBT100A (SOT-23) is the SMD version of the PN100A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the PN100A with the KSP05, KSP06, MPS651, MPS651G, MPSA05, MPSA05G, MPSA06, MPSA06G, MPSW05, MPSW05G, MPSW06, MPSW06G, ZTX690B or ZTX692B.
