-------------------------------
Usually, these are EBC (123) if they are plastic. Metal cans like shiny
top-hats are arranged the opposite way, the emitter is pointed to by the
small projecting tab from the brim. The bigger transistors, like the TIP31
and the others packaged with a heat sink like these TO-220 packages are
BCE, and the heat sink plate is also the collector. In the case of smaller
transistors, the middle pin of three or of the three out of four pin positions
used at the 6,9, and 12 o'clock positions, (looking down from above), is
base, in other words, 9 o'clock. cylindrical metal cans are usually EBC at
the 6, 9, and 12 o'clock positions from the top.

YOU REALLY *DON'T* know what a transistor does or how it works if you have
asked a question like that!!!!! Better go back to the books, quick!!!
No shame, just go and enjoy learning this stuff now!!
