Description
MOC8104 High CTR Optocoupler DIP – Phototransistor Output Isolation IC
The MOC8104 optocoupler is a high current transfer ratio (CTR) opto-isolator designed for safe signal isolation between low-voltage logic circuits and high-voltage or noisy power sections. It integrates an infrared LED and a phototransistor output in a compact DIP package, providing reliable electrical isolation and strong output drive capability. Compared to standard optocouplers, the MOC8104 offers higher CTR, making it suitable for precision control, SMPS feedback, and industrial automation systems.
