The PN2222A 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 PN2222A is the PN2907A.The BCW66 (SOT-23), DXT2222A (SOT-89), DZT2222A (SOT-223), FJX2222A (SOT-323), FMMT2222A (SOT-23), FMMT2222AR (SOT-23), KN2222AS (SOT-23), KST2222A (SOT-23), KTN2222AS (SOT-23), KTN2222AU (SOT-323), MMBT100 (SOT-23), MMBT2222A (SOT-23), MMBT2222AT (SOT-523F), MMST2222A (SOT-323), PMBT2222A (SOT-23), PMST2222A (SOT-23) and PZT2222A (SOT-223) is the SMD version of the PN2222A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the PN2222A with the BC537, BC538, MPS650, MPS650G, MPS651, MPS651G, MPSW01A, MPSW01AG, PN4033 or ZTX450.
