The SFH615A-3X009 is a surface-mount optocoupler with a phototransistor output, housed in an SMD-4 package with option 9, featuring a creepage and clearance distance of 8 mm typical. It includes a GaAs infrared emitter and silicon planar phototransistor for signal isolation between circuits, with an isolation test voltage of 5300 V RMS. The device supports a collector current of up to 50 mA, operates from -55 °C to +100 °C, and meets UL, cUL, BSI, FIMKO, and CQC agency approvals. Current transfer ratio ranges from 100% to 200% at 10 mA forward current and 5 V collector-emitter voltage. Switching times are specified for non-saturated and saturated operation, with a coupling capacitance of 0.4 pF and an input forward voltage of 1.35 V to 1.65 V. The part is designed for applications such as switchmode power supplies and telecom systems.
