Operating and Storage Junction Temperature Range: -55 to +125 °C
Package: TO-92
Pinout of 2SC923
The 2SC923 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 2SC923 transistor can have a current gain of 150 to 1000. The gain of the 2SC923-E will be in the range from 350 to 700, for the 2SC923-F it will be in the range from 225 to 450, for the 2SC923-H it will be in the range from 150 to 300, for the 2SC923-U it will be in the range from 500 to 1000.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SC923 might only be marked "C923".
Complementary PNP transistor
The complementary PNP transistor to the 2SC923 is the 2SA641.
