Where transient overvoltage protection in
sensitive equipment is required, such as:
Features
Description
In order to prevent fast transients from leading to
severe damages in a high speed data system, a
specific protection has been developed by
STMicroelectronics.
The USB6B1 protects the two input lines against
overvoltage. Besides, this device also keeps the
power rails in a safe limit thanks to the integrated
Transil diode.

... CC possible to avoid overvoltages due to parasitic phenomena (see It’s often harder to connect the power supply near to the USB6B1 unlike the ground thanks to the ground plane that allows a short connection. To ensure the same efficiency for positive surges when the connections can’t be short enough, we recommend to putting a ...
