The PS2561DL-1Y-F3-A/W is a single-channel optocoupler that uses a infrared light emitting diode (LED) and a silicon phototransistor. It is designed and manufactured by RENESAS, a world leader in semiconductor products and electronics. The optocoupler is constructed as a surface-mount device (SMD) and has an insulation voltage of 5kV and a collector-emitter voltage of 80V. It is used in isolating and coupling transistor outputs. This optocoupler features Gallium Arsenide Phosphide-hosted and AlGaAs infrared LED with fast response times and a high phototransistor collector current gain. It is suitable for a wide range of applications in high-speed switching, level-shifting, and noise suppression.
