PS2705-1-F3-M-A

Overview

The PS2705-1-F3-M-A is a single-channel optocoupler from the Renesas NEPOC series, featuring an AC/DC input and NPN phototransistor output. It provides 3750Vrms isolation voltage with a typical current transfer ratio of 100%. Key electrical parameters include a maximum collector-emitter voltage of 40V, peak forward current of 50mA, and saturation voltage of 300mV. The device supports surface mount installation in a 4-SOP package, operating within a temperature range of -55°C to 100°C.

Feature Summary

Supports AC and DC input signals for versatile control applications
Provides high isolation voltage capability for safety-critical circuits
Features a shielded SOP package to block ambient light interference
Delivers high-speed switching performance suitable for data transmission

Applications

Solid-state relay driver circuits
Microcontroller interface isolation
Industrial communication bus isolation
Power supply feedback loops

Procurement Notes

Verify the specific suffix 'M-A' against official Renesas documentation to confirm pinout and packaging details, as variations exist within the PS2705 family. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into regulated equipment designs.

Selection Notes

Select this component when AC input response is required alongside standard transistor output characteristics. Compare the 40V collector-emitter voltage rating against load requirements. Evaluate the 100% typical CTR against drive current limitations. Consider the 4-SOP package dimensions for board space constraints compared to alternative isolation technologies.

Part Context

This part belongs to the PS2705 series of high-isolation voltage photocouplers manufactured by Renesas Electronics. The series utilizes a GaAs LED coupled with an NPN silicon phototransistor. The NEPOC designation indicates its classification within Renesas's optoelectronic portfolio designed for density mounting and reliable signal transmission across isolation barriers.
