USB6B1

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.

Key Features

Full diode bridge with integrated clamping protection
Peak pulse power dissipation: P_PP = 500 W (8/20 µs)
Breakdown voltage: V_BR = 6 V min.
Very low capacitance, compatible with high debit data or signal rates.
