PS2732-1-F3

Overview

The PS2732-1-F3 is a high collector-to-emitter voltage SOP multi-photo coupler manufactured by CEL. It features a GaAs LED and an NPN silicon Darlington-connected phototransistor. Key electrical parameters include a maximum collector-emitter voltage of 300 V, a maximum collector current of 150 mA, and a typical forward voltage of 1.4 V. The device offers a high isolation voltage of 2500 Vrms and operates within a temperature range of -55°C to 100°C.

Feature Summary

• High isolation voltage capability for safe signal transmission between isolated circuits
• Darlington-connected phototransistor output for high current transfer ratio
• Designed for high-density mounting in surface-mount applications

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission across isolated grounds

Procurement Notes

Verify the obsolete lifecycle status before procurement planning. Confirm regional availability as distribution may be restricted. Ensure the specific suffix matches design requirements for package and performance characteristics. Cross-reference with official datasheets for final validation.

Selection Notes

Select this component when high collector-emitter voltage and robust isolation are required in a compact SOP package. Consider the Darlington output configuration for applications needing higher gain. Verify thermal operating limits against system constraints.

Part Context

This part belongs to the PS2732 series of optically coupled isolators. It shares architectural similarities with other models in the family but is distinguished by its specific voltage ratings and Darlington output structure. The series is designed for general-purpose isolation tasks.

Replacement Considerations

Direct substitutes include PS2732-1-F3-A and PS2732-1-F4-A. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement maintains the required isolation voltage and current transfer characteristics.
