CNY75AX

Overview

The CNY75AX is a single-channel transistor output optocoupler manufactured by Isocom Components 2004 LTD. It features a phototransistor with an accessible base terminal, housed in a 6-DIP through-hole package. The device provides a high isolation voltage of 5300 Vrms and supports a maximum forward current of 60 mA. Key electrical parameters include a minimum collector-emitter breakdown voltage of 90 V, a typical current transfer ratio of 63%, and a maximum dark power supply of 150 nA. It operates within a temperature range of -55 °C to 100 °C.

Feature Summary

• Integrates a phototransistor with an exposed base pin for external circuit control
• Provides robust galvanic isolation rated at 5300 Vrms
• Complies with UL recognition and VDE approval standards

Applications

• Industrial control systems requiring signal isolation
• Microcontroller interface circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'AX' against official Isocom Components documentation to confirm exact electrical tolerances and compliance status. Ensure the procurement source provides valid datasheets matching the 6-DIP through-hole configuration. Cross-reference manufacturer part numbers to avoid confusion with surface mount variants or different series members.

Selection Notes

Select this component when a phototransistor output with base access is required for linear or switching applications. The 5300 Vrms isolation rating suits high-voltage noise environments. Consider the 63% typical current transfer ratio for drive capability requirements. Verify that the 60 mA maximum forward current aligns with the input LED specifications of the target circuit design.

Part Context

This component belongs to the transistor output optocoupler category from Isocom Components 2004 LTD. It shares the 6-DIP form factor with other devices in the manufacturer's portfolio but is distinguished by its specific AX suffix designation and photovoltaic/transistor hybrid characteristics. It serves as a discrete isolation solution for digital and analog signal transmission.
