50A Integrated PowIRstage®
METAL AND COMPONENT PLACEMENT
 Lead land width should be equal to nominal part
lead width. The minimum lead to lead spacing
should be ≥ 0.2mm to prevent shorting.
 Lead land length should be equal to maximum
part lead length +0.15 - 0.3 mm outboard
extension and 0 to + 0.05mm inboard extension.
The outboard extension ensures a large and
visible toe fillet, and the inboard extension will
accommodate
any
part
misalignment
and
ensure a fillet.
 Center pad land length and width should be
equal to maximum part pad length and width.
 Only 0.30mm diameter via shall be placed in the
area of the power pad lands and connected to
power planes to minimize the noise effect on the
IC and to improve thermal performance.
