PS2711-1-F3-L-A

Overview

The PS2711-1-F3-L-A is a photovoltaic output optoisolator manufactured by CEL. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor in a compact SMD package. The device provides high isolation voltage of 3,750 Vrms and features a typical current transfer ratio of 200% at 1mA forward current. It is designed for applications requiring reliable signal transmission with electrical isolation.

Feature Summary

• High current transfer ratio for efficient signal coupling
• High isolation voltage capability for safety
• Compact surface mount packaging for density

Applications

• Industrial control systems
• Power supply feedback loops
• Signal isolation in communication interfaces

Procurement Notes

Verify the specific suffix -F3-L-A to ensure correct tape and reel packaging and lead-free compliance. Confirm availability status as some variants may be discontinued. Check RoHS compliance documentation for regulatory requirements. Ensure the ordering part number matches the required isolation and CTR specifications exactly.

Selection Notes

Select this component when high CTR and robust isolation are critical. The photovoltaic output type offers low leakage current. Consider the SMD form factor for automated assembly. Verify thermal performance within the operating temperature range. Ensure input current limits are respected for LED longevity.

Part Context

This part belongs to the PS2711 series of NEC/CEL optoisolators. It is a single-channel device using a 4-SMD gull wing package. The series is known for high reliability in industrial environments. It serves as a replacement for older through-hole equivalents in modern PCB designs.

Replacement Considerations

Direct substitutes include PS2711-1-F3-K or PS2711-1-V-M-A if pinout and electrical characteristics match. Verify package dimensions and isolation voltage ratings before substitution. Check manufacturer datasheets for equivalent performance metrics.
