Description
CNY17-2 Optocoupler DIP-6 – Reliable Phototransistor Opto-Isolator IC
The CNY17-2 Optocoupler is a phototransistor output opto-isolator IC that combines an infrared LED and a silicon phototransistor inside a compact DIP-6 through-hole package. It provides effective electrical isolation between low-voltage control electronics and high-voltage or noisy power circuits, protecting sensitive components from voltage spikes, transients, and ground-loop interference. The CNY17-2 is widely used in industrial control systems, SMPS feedback circuits, relay drivers, PLC input modules, and microcontroller signal isolation where stable current transfer and long-term reliability are required.
