  • 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: PPP = 500 W (8/20 µs)
    • Breakdown voltage: VBR = 6 V min.
    • Very low capacitance, compatible with high debit data or signal rates.
