PS2711-1-A

Overview

The PS2711-1-A is a high-isolation voltage photoMOS relay manufactured by Renesas Electronics Corporation. It features a single-pole double-throw (SPDT) normally-open contact configuration driven by an infrared LED. The device provides electrical isolation between the input control circuit and the output load circuit, ensuring safe operation in sensitive electronic applications. Key specifications include a maximum on-resistance of 30 ohms at room temperature and a breakdown voltage of 400 volts AC between contacts. The unit operates within a wide temperature range and is designed for compact surface-mount packaging.

Feature Summary

• Provides galvanic isolation between input and output circuits using infrared light coupling technology
• Features a SPDT normally-open contact structure for versatile switching capabilities
• Designed with high dielectric strength to protect low-voltage control systems from high-voltage loads

Applications

• Industrial automation control systems requiring isolated switching
• Test and measurement equipment needing reliable signal routing
• Medical devices demanding strict safety isolation standards

Procurement Notes

Verify the specific suffix -1-A against official Renesas documentation to confirm pinout and package type. Ensure compatibility with operating voltage and current ratings before integration. Check for RoHS compliance status if required by your manufacturing standards. Confirm storage conditions and handling precautions to prevent electrostatic discharge damage during assembly.

Selection Notes

Consider the on-resistance value when calculating power dissipation in the load circuit. Evaluate the isolation voltage requirements against the system's safety standards. Assess the switching speed limitations compared to mechanical relays or other solid-state alternatives. Verify that the input forward current matches the available drive capability of the control microcontroller or logic gate.

Part Context

This component belongs to the PS2711 series of photoMOS relays, which are designed for general-purpose switching applications. The series offers various configurations including single-pole double-throw and dual single-pole single-throw options. These devices are commonly used in environments where mechanical wear and arcing must be eliminated while maintaining high reliability and long operational life.

Replacement Considerations

Check for direct cross-references from manufacturers like Omron or Sharp. Verify pin compatibility and isolation voltage ratings before substitution. Ensure the replacement part meets the same thermal and electrical specifications.
