Recommended Pad Layout
TBU ? High-Speed Protectors have a 100 % matte-tin termination
?nish. For improved thermal dissipation, the recommended layout
uses PCB copper areas which extend beyond the exposed solder
pad. The exposed solder pads should be de?ned by a solder mask
which matches the pad layout of the TBU ? device in size and spac-
ing. It is recommended that they should be the same dimension as
the TBU ? pads but if smaller solder pads are used, they should be
centered on the TBU ? package terminal pads and not more than
0.10-0.12 mm (0.004-0.005 in.) smaller in overall width or length.
Solder pad areas should not be larger than the TBU ? pad sizes
stencil thickness is 0.10-0.12 mm (0.004-0.005 in.) with a stencil
opening size 0.025 mm (0.0010 in.) less than the solder pad
size. Extended copper areas beyond the solder pad signi?cantly
improve the junction to ambient thermal resistance, resulting in
operation at lower junction temperatures with a corresponding
bene?t of reliability. All pads should soldered to the PCB, includ-
ing pads marked as NC or NU but no electrical connection should
be made to these pads. For minimum parasitic capacitance, it is
recommended that signal, ground or power signals are not routed
beneath any pad.
to ensure adequate clearance is maintained. The recommended
