Additional Details

The PS2561A-1Y-V-A/JT utilizes an infrared light-emitting diode (LED) optically coupled to a phototransistor. When current flows through the LED, it emits infrared light, which activates the phototransistor. This allows for the transfer of signals between two electrically isolated circuits. The '1Y' in the part number signifies a specific CTR rank, 'V' indicates a high isolation voltage option, and 'A/JT' may relate to specific packaging or testing parameters. The operating temperature range is typically -55°C to +110°C. It conforms to safety standards such as UL, CSA, and VDE. Detailed specifications, including CTR values, input forward voltage, and output saturation voltage, can be found in the manufacturer's datasheet.
