PC817 DIP 35V 50mA Optoisolator / Optocoupler

Product Description: PC817 DIP 35V 50mA Optoisolator

The PC817 is a phototransistor optoisolator in a DIP (Dual Inline Package) designed to provide electrical isolation between different parts of a circuit. With a maximum input voltage of 35V and a current rating of 50mA, this optoisolator is ideal for applications that require signal isolation, noise reduction, and protection between high- and low-voltage sections of electronic systems. The PC817 optoisolator uses an infrared LED to transmit signals to a phototransistor, enabling non-contact signal transfer while maintaining electrical isolation.

The PC817 features a high current transfer ratio (CTR), ensuring efficient signal transmission with minimal distortion or loss of signal strength. It is widely used in microcontroller interfaces, relay drivers, signal processing, and switching power supplies to protect sensitive low-voltage circuits from high-voltage spikes and surges. The DIP package makes it easy to integrate into standard through-hole PCB designs, ensuring ease of use in a variety of applications.

Key Features:

• Voltage Rating: Operates with an input voltage of up to 35V, suitable for a wide range of applications.
• Current Rating: Can handle up to 50mA of input current, making it suitable for low- to moderate-power circuits.
• Electrical Isolation: Provides optical isolation between high-voltage and low-voltage parts of the circuit, ensuring safety.
• High CTR (Current Transfer Ratio): Delivers efficient signal transmission with high current gain.
• Package Type: DIP-4 package, ideal for easy integration into through-hole PCB designs.
