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