PS2711-1-F3-K-A

Overview

The PS2711-1-F3-K-A is a single-channel optoisolator manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode with an NPN silicon phototransistor within a compact four-pin Small Outline Package (SOP). The device provides high isolation voltage of 3,750 Vrms and achieves a typical current transfer ratio of 200% at a forward current of 1mA.

Feature Summary

• High current transfer ratio for efficient signal transmission
• High isolation voltage capability for safety
• Compact and thin four-pin SOP package design

Applications

• Digital isolation applications requiring reliable signal transmission
• Solar power systems
• Industrial control equipment

Procurement Notes

Verify the specific suffix F3-K-A against official datasheets to confirm pinout and packaging details. Confirm availability status as distributors may list discontinued items. Ensure compatibility with required isolation voltage standards for the target application environment before procurement.

Selection Notes

Select this component when high density and small form factor are required alongside robust electrical isolation. The transistor output type suits digital switching applications. Verify that the 3,750 Vrms isolation rating meets system safety requirements and that the SOP package fits the PCB layout constraints.

Part Context

This part belongs to the PS2711 series of optically coupled isolators. The series typically features GaAs LEDs paired with silicon phototransistors in plastic packages. Variations exist with different suffixes indicating packaging or compliance attributes, but core functionality remains consistent across the family.

Replacement Considerations

Direct substitutes include PS2711-1-K-A and PS2711-1-F3-M-A. Verify pin compatibility and electrical parameters before substitution. Note that some variants may be discontinued; check current manufacturer availability for alternative sourcing.
