Pinout of 2SC1959-O
The 2SC1959-O 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. Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SC1959-O transistor can have a current gain of 70 to 140. The gain of the 2SC1959 will be in the range from 70 to 400, for the 2SC1959-GR it will be in the range from 200 to 400, for the 2SC1959-Y it will be in the range from 120 to 240.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SC1959-O might only be marked "C1959-O".
Complementary PNP transistor
The complementary PNP transistor to the 2SC1959-O is the 2SA562TM-O.
