Introduction to General-Purpose Products for Desktop PCs

NEC Electronics offers a variety of small, low on-resistance Power MOSFETs mounted on motherboards. Lower on-resistance and a smaller gate electric charge than conventional products has been achieved by adopting the 0.25 μm process “UMOS4”. Mounted on small packages TO-251 and TO-252, the Power MOSFETs are suitable for CPU power supplies on motherboards.
ESD measures are becoming indispensable in the desktop and PC area, where the trend for high-clock CPUs and high-speed interfaces is accelerating every year. NEC Electronics offers the NSDA and NNCD series as ESD protective devices. The NSDA series is suitable for use in high-speed interfaces, and its low terminal capacitance gives ESD protection without affecting high-speed data transfer. The NNCD series that employs a flat lead package is suitable for ESD protection for small devices that require high-density mounting. The maximum height of the package is 0.5 mm. Mounting area can be reduced by 50% for two pins and by 38% for five pins (our super small-sized mold ratio).
