The PC817 is a high-density mounting type photocoupler designed to provide electrical isolation between different stages of a circuit while enabling signal transfer via light. This photocoupler uses an infrared LED and a phototransistor to transmit data or control signals with minimal electrical connection between the input and output stages, which helps protect sensitive components from high voltages or surges.
Ideal for use in high-speed switching, signal isolation, and voltage level shifting, the PC817 is commonly used in microcontroller interfacing, AC mains isolation, and signal transmission in digital circuits. Its compact size and high isolation voltage make it suitable for space-constrained applications.
High-Speed Switching: Supports fast data transmission with quick response times.
High Isolation Voltage: Provides up to 5kV isolation between input and output for protection.
Compact Package: The DIP-4 package makes it suitable for high-density mounting and space-efficient applications.
Low Input Current: Requires low input current to trigger the LED, improving power efficiency.
Wide Operating Temperature Range: Operates efficiently in various environments with temperatures ranging from -30°C to +100°C.
Phototransistor Output: Provides fast and reliable switching capabilities, suitable for low-voltage digital logic systems.
RoHS Compliant: Environmentally friendly and compliant with regulatory standards.
Microcontroller Interfacing: Isolating digital signals between low-voltage systems and high-voltage environments.
AC Mains Isolation: Protects low-voltage components from high-voltage AC systems.
Signal Isolation in Switching Circuits: Prevents noise and high voltage from affecting downstream circuits.
Switching Power Supplies: Used in feedback loops for power regulation and voltage monitoring.
Relays and Circuit Protection: Isolates circuits to prevent damage from voltage spikes or surges.
