Overview
The CNY17F4SR2VM is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and operates in surface-mount 6-pin SMD packages, including gull-wing configurations. The device provides an isolation voltage of 4170 Vrms and supports a maximum forward current of 60 mA with a typical forward voltage of 1.35 V to 1.65 V. Key electrical parameters include a collector-emitter saturation voltage of 400 mV maximum, a collector current capacity of 50 mA, and a collector-emitter voltage rating of 70 V. The current transfer ratio ranges from 160% to 320%. Operating temperatures span from -40°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits via an internal LED and phototransistor structure.
- Features a compact surface-mount package design suitable for automated assembly processes.
- Delivers fast switching performance with defined rise and fall times for signal transmission applications.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic devices
- Power supply feedback loops
Procurement Notes
Verify the specific suffix SR2VM corresponds to the required tape-and-reel packaging configuration. Confirm that the 6-SMD gull-wing footprint matches the target PCB layout. Ensure compliance with RoHS3 directives if environmental regulations apply to the final assembly. Cross-reference datasheet revisions to confirm insulation ratings remain consistent with system safety requirements.
Selection Notes
Select this component when a surface-mount solution is required for galvanic isolation. The 4170 Vrms rating suits applications demanding robust barrier protection. Verify that the 160% minimum current transfer ratio meets the drive requirements of the receiving circuit. Consider the thermal dissipation limits within the enclosed package space during operation.
Part Context
This part belongs to the CNY17 series of optocouplers, which are widely used for general-purpose isolation. The F4 designation typically indicates a specific current transfer ratio bin compared to other variants like F1 or F2. The SR2VM suffix denotes the surface-mount variant with reel packaging, distinguishing it from through-hole DIP versions.
Replacement Considerations
CNY17F4M serves as the through-hole equivalent with identical electrical characteristics but different mounting style. CNY17F2SR2VM offers a lower current transfer ratio range (63%-125%) while maintaining the same package and isolation voltage.
