PC817SC 35V 5kV 50mA 0.1V@20mA,1mA 1 6V 1.2V SOP-4 Transistor, Photovoltaic Output Optoisolators SMD
The PC817SC is a high-reliability surface-mount optocoupler designed to provide electrical isolation between input and output circuits while maintaining efficient signal transfer. It integrates an infrared emitting diode optically coupled to a phototransistor, enabling safe communication between low-voltage control circuits and high-voltage power systems.
Features:
- High isolation voltage up to 5kVrms for superior electrical protection.
- Maximum collector-emitter voltage of 35V for reliable switching.
- Collector current capability up to 50mA.
- Low forward voltage of approximately 1.2V for efficient operation.
- Low saturation voltage of 0.1V@20mA,1mA.
- Phototransistor output with stable current transfer characteristics.
