The 2SA984K 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 2SA984K transistor can have a current gain of 60 to 320. The gain of the 2SA984K-D will be in the range from 60 to 120, for the 2SA984K-E it will be in the range from 100 to 200, for the 2SA984K-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA984K might only be marked "A984K".The complementary NPN transistor to the 2SA984K is the 2SC2274K.The 2SA1368 (SOT-89) is the SMD version of the 2SA984K transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA984K with the 2SA1275, 2SB560, 2SB647, KSA1013 or KTA1275.
