USB6Bx
DATA LINES PROTECTION
Application Specific Discretes A.S.D.
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 n Full diode bridge with integrated clamping protection n Breakdown voltage : VBR = 6V min. n Peak pulse power dissipation : PPP = 500W (8/20µs) n 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 USB6Bx protects the two input lines against overvoltage.
