CNY17F4SR2M

Overview

The CNY17F4SR2M is a single-channel transistor output optocoupler from onsemi, designed for surface-mount applications in a 6-SMD gull-wing package. It provides an isolation voltage of 4170Vrms and operates within a temperature range of -40°C to +100°C. The device features a DC input with a maximum forward current of 60mA and a typical forward voltage of 1.35V. Output specifications include a collector-emitter breakdown voltage of 70V, a maximum collector current of 50mA, and a saturation voltage of 400mV. Current transfer ratios range from 160% to 320% at 10mA input, with typical rise and fall times of 4µs and 3.5µs respectively.

Feature Summary

• High isolation voltage capability of 4170Vrms for robust circuit separation
• Surface-mount 6-SMD gull-wing packaging for automated assembly integration
• Wide operating temperature range supporting industrial environmental conditions

Applications

• General-purpose signal isolation in electronic circuits
• Interface between microcontrollers and high-voltage loads
• Power supply feedback loop isolation

Procurement Notes

Verify the specific suffix SR2M confirms the surface-mount reel or cut-tape packaging configuration required for your assembly line. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) against your storage and reflow soldering profiles. Ensure the 6-SMD gull-wing footprint matches your PCB design guidelines before finalizing procurement orders.

Selection Notes

Select this component when surface-mount technology is required for the CNY17F4 series functionality. The 4170Vrms isolation rating suits applications demanding higher safety margins than standard 5000VAC devices might offer in compact packages. Consider the 50mA collector current limit and 160-320% CTR range to ensure adequate drive capability for downstream logic or relay interfaces without exceeding thermal dissipation limits.

Part Context

This part belongs to the CNY17F4 family of transistor output optocouplers manufactured by onsemi. It serves as the surface-mount equivalent to through-hole variants like the CNY17F4M, maintaining identical electrical characteristics while adapting to SMD assembly processes. The device is widely used in industrial control systems where space constraints and automated manufacturing efficiency are prioritized over manual insertion techniques.

Replacement Considerations

Direct pin-compatible replacements within the same manufacturer family include other CNY17F4 variants with different packaging suffixes. Cross-manufacturer equivalents should be verified for matching isolation voltage, CTR ranges, and package dimensions to ensure functional interchangeability without redesigning the host circuit board.
