Pinout of 2SC1842E
The 2SC1842E 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 2SC1842E transistor can have a current gain of 400 to 800. The gain of the 2SC1842 will be in the range from 200 to 1200, for the 2SC1842F it will be in the range from 300 to 600, for the 2SC1842P it will be in the range from 200 to 400, for the 2SC1842U it will be in the range from 600 to 1200.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SC1842E might only be marked "C1842E".
