The 2SA1123-T 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 2SA1123-T transistor can have a current gain of 260 to 450. The gain of the 2SA1123 will be in the range from 130 to 450, for the 2SA1123-R it will be in the range from 130 to 220, for the 2SA1123-S it will be in the range from 185 to 330.Sometimes the "2S" prefix is not marked on the package - the 2SA1123-T might only be marked "A1123-T".You can replace the 2SA1123-T with the 2SA1124, 2SA1124-T, 2SA1285A, 2SA1285A-F, 2SA1376, BF421, BF423 or KTA1279.
