USB
USB 3.0 - ESD & Overcurrent Protection
Solution Products
Objective
Universal Serial Bus (USB) 3.0 ports provide
up to 5 Gbps data transfer rates and 5 V
power at up to 900 mA. As a hot-pluggable
interface, it typically requires protection
against ESD and short circuits. This solution
provides this protection.
Solution
1 Multifuse? PPTC Resettable Fuse:
MF-NSMF200-2
1 TVS Diode Array: CDDFN10-0506N
Compliance
USB 3.0
UL60950
IEC 61000-4-2 Level 4 (8 kV / 15 kV)
