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 USB6Bx 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.

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

APPLICATIONS
Where transient overvoltage protection in sensitive equipment is required, such as:
- Universal Serial Bus ports
- RS-423 interfaces
- RS-485 interfaces
- ISDN equipment
- T1/E1 line cards
- HDSL / ASDL interfaces

BENEFITS
◾ Provides protection for each line and between the supply voltage and GND : 25A , 8/20µs.
◾ High ESD protection level : up to level 3 per MIL STD 883C-Method 3015-6
◾ Separated inputs and outputs (so-called 4-point structure) to improve ESD susceptibility.
◾ Comprehensive package pin-out for immediate implementation.
