Additional Details

The PS2505-1-A(NJ) features a current transfer ratio (CTR) ranging from 80% to 160% at an input current of 5 mA. Its isolation voltage is rated at 5000 Vrms for one minute. The optocoupler consists of an infrared LED and a phototransistor. When current flows through the LED, it emits light, which activates the phototransistor. The electrical signal is transferred from the input to the output side without any direct electrical connection. This provides excellent electrical isolation. The device is housed in a 4-pin DIP package and is suitable for through-hole mounting. The PS2505-1-A(NJ) is designed for applications where safety and electrical isolation are critical requirements.
