CNY17F-4XSMT&R

Overview

The CNY17F-4XSMT&R is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a surface-mount DIP package with six pins and utilizes a transistor output configuration. The device provides an isolation voltage of 5300Vrms and supports a maximum forward current of 60 mA. Key electrical characteristics include a minimum current transfer ratio of 160% at 10 mA input, a collector-emitter saturation voltage of up to 400mV, and a maximum output voltage of 70V.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes a compact surface-mount DIP package for automated assembly
• Features a standard NPN phototransistor output for digital signal switching

Applications

• Industrial control systems requiring circuit isolation
• Power supply protection and monitoring circuits
• Smart metering and utility instrumentation
• Gas detection and environmental monitoring devices

Procurement Notes

Verify the specific suffix 'SMT&R' confirms the tape-and-reel packaging format required for your manufacturing line. Confirm that the manufacturer designation matches Isocom Components 2004 LTD exactly, as similar part numbers may exist from other vendors. Ensure the component status is active for your production timeline, as availability can vary by distributor lot.

Selection Notes

Select this component when a surface-mount solution is required for applications needing 5300Vrms isolation. The 160% minimum CTR ensures reliable switching at low drive currents. Consider the 6-pin SMD footprint constraints and verify that the 60mA forward current rating meets the interface requirements of the driving logic circuit.

Part Context

This component belongs to the CNY17 series of optocouplers, which are widely used for general-purpose isolation. Isocom Components manufactures these devices to meet industry standards, often serving as replacements for obsolete parts from other manufacturers. The series is known for providing flexible lead forms and specialized parameter selection for specific circuit designs.

Replacement Considerations

The MOC81043SD is a documented substitute option. Verify that the replacement's 5300Vrms isolation and transistor output type match the original design requirements. Check if the replacement's current transfer ratio and package dimensions are compatible with the existing PCB layout.
