The TLP521-4GB is a quad-channel optically coupled isolator comprising an infrared LED and NPN silicon phototransistors in a 16-pin DIP package. It provides 5300V RMS isolation voltage, operates from -30°C to +100°C, and features a current transfer ratio of 100% to 600% at 5mA forward current and 5V collector-emitter voltage. The device is lead-free, RoHS compliant, and meets UL and VDE safety approvals. Surface mount and tape & reel options are available for the series, but the GB grade specifies medium-high CTR performance. The part includes a collector-emitter saturation voltage of 0.4V at 1mA forward current and 0.2mA collector current.
