SATA HDD Interface Data & Power Protection Solution Products MF-MSMF075/24-2 Objective Compliance SATA Hard Disk Drives are typically powered from 5 VDC. The power line needs transient, inrush and reverse polarity protection. There are also data lines susceptible to damage from ESD events when the drive is not connected. IEC 61000-4-2 ESD Level 4, 8 kV Solution Benefit 1 Multifuse® PPTC Resettable Fuse: MF-MSMF075/24-2 1 TVS Diode: SMBJ5.0A 1 TVS Diode Array: CDDFN10-0524P This solution provides surge, inrush and reverse polarity protection on the power line and ESD protection on the data lines. Alternate Recommendations HDD powered from 12 VDC would instead use a model SMBJ12A TVS Diode on the power line.
