USB6B1

Data line protection

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

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.

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. Besides, this device also keeps the

power rails in a safe limit thanks to the integrated

Transil diode.

Benefits

■ Provides protection for each line and between

the supply voltage and GND: 25 A, 8/20 µs.

■ 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.
