Overview
The CNY17F3SR2M is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output with no base connection, housed in a surface-mount 6-SMD package. The device provides an isolation voltage of 4170 Vrms and supports a maximum forward current of 60 mA. Key electrical parameters include a collector-emitter saturation voltage of up to 400 mV and a typical rise/fall time of 4 µs/3.5 µs. The unit operates within a temperature range of -40°C to 100°C.
Feature Summary
- Provides robust electrical isolation between input and output circuits using a phototransistor configuration.
- Designed for surface-mount assembly to facilitate compact circuit board layouts.
- Features a high current transfer ratio to ensure reliable signal transmission across the isolation barrier.
Applications
- Industrial automation control systems
- Power supply feedback loops
- Signal isolation in microcontroller interfaces
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for recent process change notifications regarding packaging or material composition. Ensure storage conditions meet moisture sensitivity level requirements prior to soldering.
Selection Notes
Select this component when a surface-mount solution is required for galvanic isolation. Compare the 4170 Vrms isolation rating against system safety standards. Evaluate the 60 mA forward current limit and phototransistor output characteristics against load requirements. Consider the operating temperature range for environmental compatibility.
Part Context
This part belongs to the CNY17F3 series of transistor output optocouplers from onsemi. The series utilizes arsenide gallium infrared LEDs coupled with NPN phototransistors. The SR2 suffix indicates specific tape-and-reel packaging configurations suitable for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical specifications before considering alternative generic optocouplers.
