TBU
suggested layout should use Non-Solder Mask Defi ne (NSMD).
The recommended stencil thickness is 0.10-0.12 mm (.004-
.005 in.) with a stencil opening size 0.025 mm (.0010 in.) less
than the device pad size. As when heat sinking any power
device, it is recommended that wherever possible, extra PCB
copper area is allowed. For minimum parasitic capacitance, do
not allow any signal, ground or power signals beneath any of
the pads of the device.
Dark grey areas show added PCB copper area for better
thermal resistance.
