The 2SA709G 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 2SA709G transistor can have a current gain of 200 to 400. The gain of the 2SA709 will be in the range from 40 to 400, for the 2SA709O it will be in the range from 70 to 140, for the 2SA709R it will be in the range from 40 to 80, for the 2SA709Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA709G might only be marked "A709G".The complementary NPN transistor to the 2SA709G is the 2SC1009G.The KSA709G is the TO-92 version of the 2SA709G.You can replace the 2SA709G with the KSA709 or KSA709G.
