mask defi ne (NSMD). Recommended stencil thickness is 0.10-0.12 mm (.004-.005 in.) with
stencil opening size 0.025 mm (.0010 in.) less than the device pad size. As when heat sink-
ing 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.
Thermal resistance using minimal pad size, where the power is the total power dissipated in the package. Additional copper pad area to be
used for additional heatsinking is also recommended.
