PS2705-1-A

Overview

The PS2705-1-A is a single-channel optocoupler from the NEPOC series, manufactured by Renesas Electronics. It integrates a GaAs infrared LED and an NPN silicon phototransistor within a shielded SOP-4 package to block ambient light. The device supports AC and DC input signals with a typical current transfer ratio of 100%. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a peak forward current of 50 mA, and a collector current of 80 mA. It offers high isolation voltage of 3750 Vrms and operates within a temperature range of -55°C to +100°C.

Feature Summary

AC/DC Input Response
High Isolation Voltage
Ambient Light Shielding

Applications

Industrial control systems
Power supply feedback loops
Solid-state relay drivers

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status in certain regions. Confirm RoHS compliance and specific suffix designations against official datasheets before integration. Check for recent product change notifications regarding manufacturing updates or label modifications to ensure compatibility with existing designs.

Selection Notes

Select this component for applications requiring high-density mounting and reliable signal isolation between low-voltage control circuits and higher-voltage loads. Ensure the required current transfer ratio meets system gain specifications. Verify that the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the PS2705 family of high-isolation voltage photocouplers designed for cost-effective performance. It shares architectural similarities with variants like PS2705-1-F3-A but differs in packaging and specific electrical tolerances. The SOP-4 form factor allows for compact PCB layouts compared to larger DIP packages.
