CNY75AXSMT&R

Overview

The CNY75AXSMT&R is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a phototransistor output with an integrated base terminal, housed in a surface-mount DIP-6 package. The device provides 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. Operating temperatures range from -55 °C to 100 °C.

Feature Summary

• Integrates a phototransistor with a dedicated base terminal for enhanced control flexibility
• Provides robust electrical isolation suitable for high-voltage switching applications
• Designed for surface-mount assembly within a compact six-pin DIP form factor

Applications

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

Procurement Notes

Verify the specific suffix 'SMT&R' confirms the surface-mount tape-and-reel packaging configuration. Ensure compatibility with standard SMD reflow soldering profiles. Confirm that the component meets required regulatory standards such as UL recognition and VDE approval for the intended market application.

Selection Notes

Select this component when a base-controlled phototransistor output is required for faster switching or linear operation compared to standard variants. Consider the 5300 Vrms isolation rating for safety-critical designs. Evaluate the thermal dissipation capabilities within the DIP-6 package against the expected operating temperature range of -55 °C to 100 °C.

Part Context

This part belongs to the CNY75 series of transistor-output optocouplers. It shares functional similarities with through-hole versions like the CNY75AX but utilizes a surface-mount package. The series is characterized by high isolation voltages and reliable performance in industrial environments.
