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 sinking any power
device, it is recommended that, wherever possible, extra PCB copper area is allowed. For mini-
mum parasitic capacitance, do not allow any signal, ground or power signals beneath any of the
pads of the device.
