The new 30-V SiB408DK and 20-V SiB412DK join the previously released Siliconix SiB414DK, the first 8-V single n-channel power MOSFET in the PowerPAK SC-75 footprint area. On-resistance for the SiB408DK is as low as 40 mO at 10 V, while the SiB412DK offers an on-resistance down to 34 mO at 4.5 V, which is 21 % lower than the closest competing device.
The devices released today include the industry’s first 30-V device in the 1.6-mm by 1.6-mm footprint area, and a 20-V MOSFET with the industry’s lowest on-resistance.
For designers, the smaller size of the PowerPAK SC-75 saves space and reduces power consumption in portable electronics, allowing for increased functionality while meeting consumer expectations for battery run times.
Typical applications for the n-channel PowerPAK SC-75 power MOSFETs will include load, PA, and battery switches in portable electronics. The devices will also save space in 1/8th or 1/16th bricks compared to common 3 mm by 3 mm packages. The SiB408DK will also be used for load switching in notebook computers and netbooks.
