Operating and Storage Junction Temperature Range: -55 to +150 °C
Package: TO-92
Pinout of 2SA709
The 2SA709 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.
Classification of hFE
The 2SA709 transistor can have a current gain of 40 to 400. The gain of the 2SA709G will be in the range from 200 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.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SA709 might only be marked "A709".
Complementary NPN transistor
The complementary NPN transistor to the 2SA709 is the 2SC1009.
