The KSD227 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 KSD227 transistor can have a current gain of 70 to 400. The gain of the KSD227G will be in the range from 200 to 400, for the KSD227O it will be in the range from 70 to 140, for the KSD227Y it will be in the range from 120 to 240.The complementary PNP transistor to the KSD227 is the KSA642.The 2SD227 is the TO-92 version of the KSD227.You can replace the KSD227 with the 2SD227, 2SD471A, MPS6532, MPS6601, MPS6601G, MPS6602, MPS6602G, MPSW01, MPSW01A, MPSW01AG or MPSW01G.
