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.
The TO-220 package is universally preferred for all commercial-
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
existing surface mount package. The D2Pak is suitable for high
current applications because of its low internal connection
resistance and can dissipate up to 2.0W in a typical surface
mount application.
The through-hole version (IRF634NL) is available for low-
profile application.
