P - 9508 IRLMS503 HEXFET Power MOSFET l l l l Generation V Technology Micro6 Package Style Ultra Low R S(on) N-Channel MOSFET 2 6 5 A V SS = 30V escription Fifth Generation HEXFET power MOSFETs from International Rectifier utilize advanced processing techniques to achieve extremely low on-resistance per silicon area. This benefit, combined with the fast switching speed and ruggedized device design that HEXFET power MOSFETs are well known for, provides the designer with an extremely efficient and reliable device for use in a wide variety of applications. G 3 4 Top View S R S(on) = 0.0Ω The Micro6 package with its customized leadframe produces a HEXFET power MOSFET with R S(on) 60% less than a similar size SOT-23. This package is ideal for applications where printed circuit board space is at a premium. It's unique thermal design and R S(on) reduction enables a current-handling increase of nearly 300% compared to the SOT-23. Micro6 Absolute Maximum Ratings Parameter Max.
