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

• (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
