Bourns Releases New PortNote® Solution and Design Kit
for USB 3.1 Interfaces
Riverside, California - May 3, 2016 - Bourns is pleased to
announce the release of the PortNote® Solution and
Design Kit for USB 3.1 Interfaces. This PortNote® Solution
shows an ultra-low capacitance six-channel TVS and
Steering Diode Array for protecting the DC bus, data and
high-speed ports from up to 10 KV contact ESD surges.
This PortNote® Solution also recommends a 2 Amp
1206-sized Polymeric PTC Resettable Fuse for overcurrent
protection of the DC bus as recommended by the USB 3.1
standard.

The TVS diode array (CDDFN10-0516P) provides
ESD and surge protection to the port. Customers
should evaluate the effects of the capacitance of the
TVS diode arrays on the quality of USB 3.1 data
flow in their specific circuits and applications.

*1.The Bourns® Model CDDFN10-0516P has been
tested according to the IEC 61000-4-2 standard
using the IEC 61000-4-2 ESD pulse waveform. The
device withstands up to 10 kV contact and 15 kV
air discharge which meets and exceeds Level 4
requirements (8 kV contact , 15 kV air).
2. The Multifuse® device (MF-NSMF200-2) helps to
ensure the application’s compliance to
A. USB 3.1 (section 11.4.1.1.1) in that a
Polymer PTC device may be used for
overcurrent protection of the DC bus; and
B. UL 60950-1 Section 2.5 (Limited Power
Source Table 2B) in that any short circuit
current shall be limited to less than 8 A
within 5 seconds.
The schematic shown here illustrates the application
protection and does not constitute the complete
circuit design. Customers should verify actual device
performance in their specific applications.

Universal Serial Bus (USB) 3.1 ports at 10 Gbps are
twice as fast as USB 3.0 ports, enhancing consumer
applications requiring low latency high bandwidth. The
USB 3.1 standard section 6.1 recommends that power
and signal lines receive ESD protection, while section
11.4.1.1 also requires that hosts and self-powered
hubs have time delayed overcurrent protection such as
Polymer PTC devices.
