DATA LINES PROTECTION

APPLICATIONS

Where transient overvoltage protection in sensi-

tive equipment is required, such as:

- Universal Serial Bus ports

- RS-423 interfaces

- RS-485 interfaces

- ISDN equipment

- T1/E1 line cards

- HDSL / ASDL interfaces

SO8

FEATURES

Full diode bridge with integrated clamping protection

Breakdown voltage : VBR = 6V min.

Peak pulse power dissipation : P_PP= 500W (8/20µs)

Very low capacitance, compatible with high debit

data or signal rates.

DESCRIPTION

In order to prevent fast transients from leading

to severe damages in a high speed data sys-

tem, 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.

DIL8

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.
