The HSB1109S-C 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 HSB1109S-C transistor can have a current gain of 100 to 200. The gain of the HSB1109S will be in the range from 60 to 320, for the HSB1109S-B it will be in the range from 60 to 120, for the HSB1109S-D it will be in the range from 160 to 320.
Complementary NPN transistor
The complementary NPN transistor to the HSB1109S-C is the HSD1609S-C.
