Product Summary
Part Number BV
DSS
IRF7F3704 20V 0.035Ω 12A*
Seventh Generation HEXFET® power MOSFETs from
International Rectifier utilize advanced processing
techniques to achieve the lowest possible on-resistance
per silicon unit 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 device
for use in a wide variety of applications.
These devices are well-suited for applications such
as switching power supplies, motor controls, inverters, choppers, audio amplifiers and high-energy pulse
circuits.
