PC817 (LTV817) - DIP4 Optocoupler

PC817 (LTV817) - Optocoupler DIP-4

The PC817 (also known as LTV817) is an optocoupler (optical isolator) consisting of an infrared LED and a phototransistor. It provides electrical isolation between input and output, allowing safe communication between circuits with different voltage levels. It is commonly used in microcontroller applications, SMPS circuits, relay drivers, and industrial control systems. The DIP-4 package makes it easy to use on breadboards and through-hole prototype boards.
