API7721SB-13

API7721SB-13 is the wide-body build of the split-direction API7721: channel A reversed and channel B forward across a 5000VRMS UL 1577 barrier in SO-8W (Type CJ), the package Diodes certifies for single-protection 5000VRMS duty with more than 8mm creepage and clearance. It is the code for an isolated CAN or serial transceiver link - the application circuit Diodes draws for the 7721 - installed in equipment whose working voltage rules out the narrow 3750VRMS body, such as data-center and telecom power, grid metering and industrial drives. VDE figures for the wide body: 8000VPK maximum transient isolation voltage, 2121VPK repetitive peak isolation voltage and 12800VPK surge. Signal performance is the family standard: 100Mbps, independent 2.5V to 5.5V rails, default-high outputs, 150kV/us minimum CMTI, 11ns typical propagation delay, 8kV HBM ESD, and -40 to +125C operation. Selection advice: match the channel direction to your schematic first (reverse on A here, on B in the 7722SB), then let the safety specification choose SB over S; also plan around the 1000-piece reel quantity of the wide-body codes. Marking is 7721 on a 13-inch tape and reel. Parameters verified against Diodes Incorporated documentation.
