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.
