Overview
The Fairchild Semiconductor 4N27SR2M is a single-channel optocoupler featuring an NPN phototransistor output. It provides 4170 Vrms isolation voltage and supports a maximum forward current of 60 mA. The device exhibits a minimum current transfer ratio of 10% at 10 mA input. Key electrical limits include a collector-emitter breakdown voltage of 30 V, reverse voltage of 5 V, and saturation voltage of 500 mV. Operating temperature ranges from -55°C to 100°C.
Feature Summary
- Integrates a gallium arsenide infrared emitting diode with a silicon NPN phototransistor for signal transmission.
- Provides high-voltage isolation between input and output circuits to protect sensitive components.
- Designed for general-purpose digital signal isolation in compact surface-mount configurations.
Applications
- General-purpose signal isolation in digital communication interfaces
- Switching power supply feedback loops
- Microcontroller I/O isolation
Procurement Notes
Verify the manufacturer designation on the component marking; ON Semiconductor acquired Fairchild's semiconductor business. Ensure the part number suffix matches the specific tape-and-reel packaging requirements. Confirm that the 4170 Vrms isolation rating meets system safety standards. Check for RoHS compliance documentation consistent with the acquisition timeline.
Selection Notes
Select this component when a standard NPN-output optocoupler with surface-mount compatibility is required. The 4170 Vrms isolation level suits most low-to-medium voltage industrial applications. Consider the 10% CTR minimum for logic-level interfacing. Verify that the 60 mA forward current capability aligns with drive circuit limitations.
Part Context
The 4N27 series is a widely recognized family of transistor-output optocouplers. The SR2M variant specifically denotes the surface-mount DIP-6 package configuration. This model maintains the functional characteristics of the through-hole 4N27 while adapting to automated assembly processes.
Replacement Considerations
Equivalent parts include the 4N27SVM (Fairchild) and generic 4N27 equivalents from other manufacturers such as Vishay or Lite-On. Ensure replacement devices match the 6-pin SMD footprint and 30 V collector-emitter voltage rating.
