Hard Disks

Hard disks used as memory for personal computers have been expanding in capacity by leaps and bounds, and are now being employed in a wider range of applications, including mounting on DVD recorders.

Renesas Electronics offers a line-up of MOSFET products suitable for hard disk power supplies, contributing to lower power consumption.
Specifically, we supply a series of products with MOSFET + SBD in one package suitable for DC/DC converter circuits that generate various voltages, ranging from 5 V power supply voltage fed to hard disks and 1.2 to 3.3 V for internal dedicated LSIs, to negative voltage, as well as MOSFET products for series regulator circuits.

Renesas Electronics offers the NSAD and NNCD series as ESD protective devices for the external interfaces of hard disks. In particular, the NSAD series features low terminal capacitance suitable for use in high-speed interfaces, and provides ESD protection that does not affect high-speed data transfer.
