The USB6B1 from STMicroelectronics is a data line protection device in 8pin SOIC package. This device is used where transient overvoltage protection in sensitive equipment is required such as USB ports, RS423 interfaces, RS485 interfaces, ISDN equipment, T1/E1 line cards and HDSL / ASDL interfaces. It is used in order to prevent fast transients leading to severe damages in high speed data system. The USB6B1 protects two input lines against overvoltages and keeps the power rails in a safe limit. It provides protection for each line and between supply voltage and GND.
