PC817 NPN Optocoupler 4-Pin DIP
€0.65
Tax included
Standard PC817 optocoupler in a DIP-4 package with 5kVrms isolation. It combines an IR GaAs LED with an NPN phototransistor for signal galvanic isolation.
The PC817 is a standard single-channel optocoupler consisting of an infrared GaAs LED coupled to an NPN phototransistor. It provides galvanic isolation to protect low-voltage circuits (microcontrollers) from high voltages or electrical noise.
This component is ideal for digital signal isolation, simple switching tasks, and protecting I/O pins in your Arduino, Raspberry Pi, or ESP32 projects. It requires a current-limiting resistor on the LED input and a pull-up resistor on the transistor output.
