SOT428
SOT428 (also known as TO252 and DPAK) occupies
an area on the PCB which is not much larger than
the area required for SOT223. Indeed, it can be
soldered to a universal SOT223 / SOT428 pad
layout. Figures 5 and 6 show the pad and relative
component sizes. The main pad area of 20mm
2
is
the minimum practical pad size for SOT428.
SOT428 has three legs which emerge from one edge
of the plastic body. The centre leg is cropped off
close to the plastic, so it is not used for electrical
connection. The “centre leg connection” is made
from the device’s metal backplate to the main PCB
pad. The two outer legs are formed to bring them
into contact with the PCB pads for soldering.
