PC814 AC Input Optocoupler – High-Density Photocoupler with AC Input Capability

The PC814 is a high-performance photocoupler (optocoupler) designed specifically for AC input applications. It contains two back-to-back connected Gallium Arsenide (GaAs) infrared emitting diodes coupled to a silicon phototransistor. This unique bidirectional input design allows it to sense AC signals directly without the need for external rectification. It provides a high isolation voltage between input and output, ensuring the safety of your microcontrollers and low-voltage circuits from high-voltage spikes.
