FifthGenerationHEXFET®PowerMOSFETsfromInternational
Rectifier utilize advanced processing techniques to achieve
extremely low on-resistance per silicon area. This benefit,
combinedwiththefastswitchingspeedandruggedizeddevice
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.
S
TheTO-220packageisuniversallypreferredforallcommercial-
industrial applications at power dissipation levels to
approximately 50 watts. The low thermal resistance and low
package cost of the TO-220 contribute to its wide acceptance
throughout the industry.
The D2Pak is a surface mount power package capable of
accommodating die sizes up to HEX-4. It provides the highest
power capability and the lowest possible on-resistance in any
existingsurfacemountpackage. TheD2Pakissuitableforhigh
current applications because of its low internal connection
resistance and can dissipate up to 2.0W in a typical surface
mount application.
