The KSA709CY 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, collector, and base leads. Suffix "C" means center collector in KSA709Y.
Here is an image showing the pin diagram of this transistor.The KSA709CY transistor can have a current gain of 120 to 240. The gain of the KSA709C will be in the range from 70 to 400, for the KSA709CG it will be in the range from 200 to 400, for the KSA709CO it will be in the range from 70 to 140.The complementary NPN transistor to the KSA709CY is the KSC1009CY.The 2N5401S (SOT-23), DXT5401 (SOT-89), DZT5401 (SOT-223), KST5401 (SOT-23) and MMBT5401 (SOT-23) is the SMD version of the KSA709CY transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSA709CY with the 2SA1275, 2SA1319, KSA1013 or KTA1275.
