The GX817C-S with 35V 5000V -55?~+110? 50mA 18us@2mA,100O 18us@2mA,100O 0.1V@1mA,20mA 1 6V 1.2V Phototransistor DC SOP-4 Optocouplers is a photosensitive optocoupler manufactured by GUOXIN JIAPIN SEMICONDUCTOR. This optocoupler is used to transfer data and signal voltages between two different circuits without having the need for an electrical connection between the circuits. The GX817C-S is compliant with RoHS standards and has voltage and temperature ratings of 35V and -55?~+110?, respectively. This optocoupler can handle up to 50mA of current with a response time of 18us@2mA,100O 18us@2mA,100O 0.1V@1mA,20mA 1 6V 1.2V Phototransistor DC SOP-4.
