The 2SB1116 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.The 2SB1116 transistor can have a current gain of 135 to 600. The gain of the 2SB1116-K will be in the range from 200 to 400, for the 2SB1116-L it will be in the range from 135 to 270, for the 2SB1116-U it will be in the range from 300 to 600.Sometimes the "2S" prefix is not marked on the package - the 2SB1116 might only be marked "B1116".The complementary NPN transistor to the 2SB1116 is the 2SD1616.The 2SB1115 (SOT-89), 2SB1122 (SOT-89), FMMTA55 (SOT-23), KST55 (SOT-23), MMBTA55 (SOT-23), PZTA55 (SOT-223) and SMBTA55 (SOT-23) is the SMD version of the 2SB1116 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KSB1116 is the TO-92 version of the 2SB1116.You can replace the 2SB1116 with the KSB1116 or KSB1116S.
