API7720SB-13

API7720SB-13 puts the dual forward-channel API7720 configuration into the wide-body SO-8W (Type CJ), and the package change is electrical, not cosmetic: isolation rises to 5000VRMS per UL 1577, creepage and clearance exceed 8mm, and the VDE maximum working isolation voltage reaches 2121VPK against 637VPK for the narrow body. Diodes positions the wide body for reinforced and basic isolation duties at higher mains voltages, including overvoltage category I to IV at up to 600VRMS and I to III at 1000VRMS. Both channels run the same direction (2 forward / 0 reverse) at up to 100Mbps from 2.5V to 5.5V supplies, with 150kV/us minimum CMTI, 11ns typical propagation delay, 12800VPK surge isolation and a lower junction-to-ambient thermal resistance of 92.3C/W. Selection advice: choose SB codes when your safety file needs the 5000VRMS rating or 8mm creepage - typical in solar inverters, grid equipment and higher-voltage motor drives; the S codes save board width only where 3750VRMS is genuinely sufficient. Note the packing difference when planning production: SB codes ship 1000 pieces per 13-inch reel rather than 4000, marking 7720. Parameters verified against Diodes Incorporated documentation.
