USB6B1RL - DATA LINES PROTECTION

General 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.

Key Features

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