Application Information

USB3.0 Protection for Super Speed

Diﬀerential signals

data lines. Thus, a lot of kids of high speed I/O ports

can be the applications of T0516ST, especially, the

USB3.0 port.

USB3.0 is expected to transmit and receive above

5Gb/s data, which needs diﬀerential signaling. For

diﬀerential signaling, keep the diﬀerential impedance

at constant is the most importance.

ESD protection devices have an inherent junction

capacitance. Usually, this added capacitance on a

USB3.0 port will drop the impedance of the

diﬀerential pair to interfere with the signaling.

to each diﬀerential signal while being rated to handle

8kV ESD contact/air discharges as outlined in IEC

61000-4-2and providing a low clamping voltage to

protect the downstream devices.

Therefore, T0516ST is the most suitable ESD

protector for USB3.0 I/O ports and other high speed.

above 5Gb/s, I/O ports in any electronic product.

Figure 3 shows the pin connection example for

USB3.0 I/O ports.
