The KSD471A 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. The KSD471AC transistor (with suffix "C") is the center collector version of the KSD471A.
Here is an image showing the pin diagram of this transistor.The KSD471A transistor can have a current gain of 120 to 400. The gain of the KSD471AG will be in the range from 200 to 400, for the KSD471AY it will be in the range from 120 to 240.The complementary PNP transistor to the KSD471A is the KSB564A.The 2SD471A is the TO-92 version of the KSD471A.You can replace the KSD471A with the 2SD471A, BC537, MPS650, MPS650G, MPS651, MPS651G, MPS6602, MPS6602G, MPSW01, MPSW01A, MPSW01AG or MPSW01G.
