PS2705-1-F3

Overview

The PS2705-1-F3 is a single-channel optocoupler featuring an AC input response and NPN silicon phototransistor output. It provides high isolation voltage of 3,750 Vrms and a typical current transfer ratio (CTR) of 100%. The device operates within a temperature range of -55°C to 100°C and utilizes a lead-free SOP-4 package with tin/bismuth terminal finish.

Feature Summary

• AC input response capability for direct AC signal coupling
• High isolation voltage rating of 3,750 Vrms
• High current transfer ratio for efficient signal transmission
• SOP package design with ambient light shielding

Applications

• High-density mounting applications requiring compact isolation
• AC signal interface circuits
• General-purpose digital isolation

Procurement Notes

Verify the specific suffix 'F3' against manufacturer documentation to confirm lead-free status and RoHS compliance details. Ensure the ordering number matches the exact tape-and-reel or tube configuration required for your assembly process. Cross-reference the datasheet revision date to confirm parameter validity.

Selection Notes

Select this component when AC input compatibility is required alongside high isolation voltage. The SOP-4 package suits space-constrained designs. Verify that the 40V collector-emitter breakdown voltage meets the load requirements. Confirm the 80mA output current capacity is sufficient for the application.

Part Context

This part belongs to the NEC/NEC Electronics (now Renesas) PS2705 series of high-isolation voltage optocouplers. The series includes variants like PS2705-1, PS2705-2, and PS2705-4, differing primarily in pin configurations and internal circuit arrangements while sharing core isolation and speed characteristics.

Replacement Considerations

PS2705-1-E3 and PS2705-1-V-E4 are listed as related ordering numbers in official documentation. Verify pinout compatibility and electrical parameters before substitution.
