Additional Details

The PS2535L-1-F3 comes in a surface-mount package, making it suitable for automated assembly processes. It operates over a wide temperature range, making it suitable for harsh environments. The input side consists of an infrared LED, and the output side is a phototransistor. When current flows through the input LED, it emits infrared light, which activates the phototransistor, allowing current to flow in the output circuit. Key specifications include forward voltage, forward current, collector-emitter voltage, and isolation voltage. Proper design considerations, including current limiting resistors for the LED and pull-up resistors for the phototransistor, are essential for optimal performance and to ensure that the device operates within its specified limits.
