The KSA709 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 KSA709C transistor (with suffix "C") is the center collector version of the KSA709.
Here is an image showing the pin diagram of this transistor.The KSA709 transistor can have a current gain of 70 to 400. The gain of the KSA709G will be in the range from 200 to 400, for the KSA709O it will be in the range from 70 to 140, for the KSA709Y it will be in the range from 120 to 240.The complementary NPN transistor to the KSA709 is the KSC1009.The 2SA709 is the TO-92 version of the KSA709.You can replace the KSA709 with the 2SA709.
