PC814 / EL814 / PC814A Optocoupler IC...

PC814 AC Input Optocoupler – High-Density Photocoupler with AC Input CapabilityThe 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.At Electrapac (www.electrapac.com), we offer original and high-quality PC814 Optocouplers to ensure maximum safety and reliability for your power electronics and automation projects in Bangladesh.Key Features & Benefits:Bidirectional AC Input: No need to worry about polarity; perfect for sensing AC mains status.High Isolation Voltage: Provides up to 5,000 Vrms of isolation, protecting your Arduino, ESP32, or PLC from high voltage.Compact DIP-4 Package: Easy to integrate into space-constrained PCB designs.Stable Performance: Features a high Current Transfer Ratio (CTR) and low power consumption.Fast Response Time: Suitable for zero-crossing detection and high-speed signal switching.Common Applications:AC Line / Mains Monitoring and Sensing.Zero-Crossing Detection for Light Dimmers and Fan Controllers.Isolation between High-Voltage Power Supplies and Low-Voltage Control Circuits.Programmable Logic Controllers (PLC) Input Interfaces.Telephone Line Interfaces and Signal Transmission.Why Choose Electrapac?Electrapac (www.electrapac.com) is your premium source for authentic electronic components.
