The PC817 is a compact transistor output optocoupler IC designed to provide electrical isolation between input and output circuits. It integrates a high-efficiency infrared LED and a silicon phototransistor housed in a space-saving SOP-4 surface-mount package. Widely used in switching power supplies, microcontroller interfacing, signal isolation, and industrial control systems, the PC817 ensures noise immunity and circuit protection while maintaining reliable signal transmission.
Features of PC817 SMD Optocoupler:
- Provides strong electrical isolation between input and output (typically 5kV isolation voltage)
- Combines infrared LED and phototransistor in one package
- Fast switching response and high current transfer ratio (CTR)
- Ideal for signal transmission in noisy environments
- SMD (SOP-4) form factor for compact PCB designs
- RoHS compliant
