Overview
The CNY17F1SR2M is a single-channel transistor output optocoupler manufactured by onsemi. It features a surface-mount 6-SMD package with gull-wing leads. The device provides an isolation voltage of 4170Vrms and supports a maximum DC forward current of 60 mA. The phototransistor output handles up to 50 mA collector current with a maximum Vce of 70 V. Typical switching times include 2 µs turn-on and 3 µs turn-off, with rise/fall times of 4 µs and 3.5 µs respectively. The Current Transfer Ratio ranges from 40% to 80% at 10 mA input.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes a compact surface-mount package for automated assembly
- Offers fast switching speeds suitable for digital signal transmission
Applications
- Industrial control systems requiring galvanic isolation
- Signal isolation in microcontroller interfaces
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'SR2M' confirms the reel packaging format distinct from tape-and-reel variants. Confirm RoHS compliance status matches current regulatory requirements. Ensure the 6-SMD gull-wing footprint aligns with the target PCB design. Validate that the 4170Vrms isolation rating meets the safety standards of the end application.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation. Compare the 40-80% CTR range against circuit gain requirements. Consider the 6-SMD package dimensions for board space constraints. Verify that the 70V output voltage rating exceeds the load requirements. Check thermal performance within the -40°C to 100°C operating range.
Part Context
This part belongs to the CNY17 family of transistor output optocouplers. It shares functional similarities with through-hole variants but utilizes a surface-mount form factor. The device is designed for general-purpose isolation tasks where compact size and reliable switching are prioritized over high-speed analog transmission.
Replacement Considerations
Direct substitutes include other CNY17 series parts with compatible pinouts. Verify equivalent isolation voltage and CTR specifications before substitution. Ensure the replacement maintains the same surface-mount package type.
