Product offering - PowerMOS

• (1) SiliconMAX Power MOSFETs

Package Benefits• Smaller package size for the same RDS(on) value and/ or reduced

component count resulting in greater power densities (W/mm3)

• Replacement of through-hole mounting power packages withsurface mount devices

• Reduced heatsinking requirement

• Smaller size of end application

SiliconMAX MOSFETs achieve the best of both worlds -low RDS(ON) and fast switching

• for SiliconMAX powerMOSFETs, gate charge (QGD)increases much more slowlywith die size

• lower QGD means fasterswitching speeds and lowerlosses

Conventional DMOS MOSFETsonly provide low RDS(ON) or fastswitching not both



• Lower system cost and higher performance

Overall Benefit to YOUby using SiliconMAX

SiliconMAX part numbering guidePhilips Semiconductors



• (2) Ultra-low gate charge “NQ” types

BenefitsIn a comparison against competitor products with the same RDS(on)

– lower gate charge (QGD)

– faster switching

> results in lower switching loss
