The KSD261G 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 KSD261CG transistor (with suffix "C") is the center collector version of the KSD261G.
Here is an image showing the pin diagram of this transistor.The KSD261G transistor can have a current gain of 200 to 400. The gain of the KSD261 will be in the range from 120 to 400, for the KSD261Y it will be in the range from 120 to 240.The complementary PNP transistor to the KSD261G is the KSA643G.The 2SC3326 (SOT-23), 2SC3326-A (SOT-23), KTC2875 (SOT-23) and KTC2875-A (SOT-23) is the SMD version of the KSD261G transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SD261G is the TO-92 version of the KSD261G.You can replace the KSD261G with the 2N5172, 2SD261, 2SD261G, 2SD471A, 2SD471AG, KSD471A, KSD471AG, MPS3415, MPS3706, MPS650, MPS650G, MPS6532, MPS6601, MPS6601G, MPS6602, MPS6602G, MPSW01, MPSW01A, MPSW01AG or MPSW01G.
