PS2711-1-K-A

Overview

The PS2711-1-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor within a compact plastic SOP-4 package. The device provides high isolation capability with a maximum insulation voltage of 3750 Vrms. Key electrical specifications include a collector-emitter breakdown voltage of 40 V, a maximum forward current of 50 mA, and a typical current transfer ratio of 200%. The unit operates reliably across a temperature range from -55 °C to +100 °C.

Feature Summary

• High current transfer ratio for efficient signal transmission
• Compact four-pin small outline package design
• High isolation voltage rating for safety compliance

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback circuits
• Signal interface between microcontrollers and high-voltage loads

Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm exact manufacturing lot characteristics and compliance status. Ensure the component matches the required pinout and isolation ratings for the target circuit design before procurement.

Selection Notes

Select this component when a single-channel isolation solution with high CTR is required in a space-constrained environment. Consider the SOP-4 package dimensions and thermal performance limits relative to the application's power dissipation requirements and ambient operating conditions.

Part Context

This part belongs to the NEPOC series of photocouplers designed for high-density mounting applications. It represents a standard offering for general-purpose isolation tasks where reliable signal transfer and electrical safety are primary design constraints.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may not match the specific CTR or isolation voltage ratings.
