Pinout of KSA642CG

The KSA642CG 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. Suffix "C" means center collector in KSA642G.
Here is an image showing the pin diagram of this transistor.

Classification of hFE

The KSA642CG transistor can have a current gain of 200 to 400. The gain of the KSA642C will be in the range from 70 to 400, for the KSA642CO it will be in the range from 70 to 140, for the KSA642CY it will be in the range from 120 to 240.
