CNY75CX

Overview

The CNY75CX is a single-channel optoisolator manufactured by Isocom Components, featuring a photovoltaic transistor output with an integrated base connection. It utilizes a 6-pin DIP package for through-hole mounting. The device provides an isolation voltage of 5300Vrms and supports a maximum forward input current of 60 mA. Typical switching characteristics include a rise time of 2µs and a fall time of 11µs. The current transfer ratio ranges from 40% to 80%, ensuring reliable signal transmission across the isolation barrier.

Feature Summary

• Integrates a photovoltaic transistor output with a dedicated base terminal for enhanced control flexibility
• Provides high-voltage electrical isolation between input and output circuits
• Designed for direct coupling with digital logic interfaces using standard DC input signals

Applications

• Digital signal isolation in microcontroller-based systems

• Industrial control interface modules requiring galvanic separation

Procurement Notes

Verify the specific suffix designation against official Isocom documentation to confirm pinout configuration and insulation class. Ensure the selected variant matches the required isolation voltage rating for the target application environment. Cross-reference datasheet parameters such as current transfer ratio and switching times with circuit design specifications before finalizing procurement orders.

Selection Notes

Select this component when a photovoltaic transistor output with base access is required for precise control applications. Consider the 5300Vrms isolation rating for safety-critical designs. Evaluate the 6-DIP package constraints against available PCB real estate. Compare switching speeds and current transfer ratios against alternative optocouplers if higher bandwidth or gain is necessary for the specific signal path.
