The 2SA628 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 2SA628 transistor can have a current gain of 55 to 800. The gain of the 2SA628-C will be in the range from 55 to 110, for the 2SA628-D it will be in the range from 90 to 180, for the 2SA628-E it will be in the range from 150 to 300, for the 2SA628-F it will be in the range from 250 to 500, for the 2SA628-G it will be in the range from 400 to 800.Sometimes the "2S" prefix is not marked on the package - the 2SA628 might only be marked "A628".You can replace the 2SA628 with the 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, MPS3638 or PN3638.
