The 2SD471AG 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 2SD471AG transistor can have a current gain of 200 to 400. The gain of the 2SD471A will be in the range from 70 to 400, for the 2SD471AO it will be in the range from 70 to 140, for the 2SD471AY it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SD471AG might only be marked "D471AG".The complementary PNP transistor to the 2SD471AG is the 2SB564AGR.The KSD471AG is the TO-92 version of the 2SD471AG.You can replace the 2SD471AG with the BC537, BC537-25, KSD471A, KSD471AG, MPS650, MPS650G, MPS651, MPS651G, MPS6602, MPS6602G, MPSW01, MPSW01A, MPSW01AG, MPSW01G or ZTX690B.
