RV1S2281ACCSP-10YV#KC0

Overview

The RV1S2281ACCSP-10YV#KC0 is a transistor output optocoupler from Renesas Electronics, featuring a GaAs LED and NPN silicon phototransistor. It provides high isolation voltage of 5000 Vrms and operates at data rates up to 15 Mbps with high common mode rejection. The device utilizes a compact 4-pin LSSOP package with extended creepage distance of 8.2 mm. It supports an operating ambient temperature range up to 115 °C and includes active high output functionality for reliable signal transmission in isolated environments.

Feature Summary

• High isolation voltage capability of 5000 Vrms for robust electrical separation
• Compact 4-pin LSSOP package design with 8.2 mm creepage distance
• High speed operation supporting data rates up to 15 Mbps
• Extended thermal performance allowing operation at ambient temperatures up to 115 °C

Applications

• Industrial automation control systems requiring galvanic isolation
• Communication interfaces needing high-speed signal transfer
• Power supply feedback circuits for voltage monitoring
• Microcontroller input/output isolation protection

Procurement Notes

Verify the specific suffix KC0 against official Renesas documentation to confirm pin configuration and packaging details. Ensure compatibility with existing PCB footprints for the 4-pin LSSOP format. Check RoHS compliance status through manufacturer declarations. Confirm availability through authorized distributors as stock levels vary. Validate that the 5000 Vrms rating meets system insulation requirements.

Selection Notes

Choose this component when high isolation voltage and moderate speed are required in a small form factor. The 8.2 mm creepage distance offers enhanced safety compared to standard packages. Consider the 115 °C operating limit for high-temperature environments. The transistor output type suits digital switching applications rather than analog linear transmission.

Part Context

This part belongs to the RV1S2281A series of optocouplers designed for general-purpose isolation. It represents Renesas' focus on compact, high-reliability components for industrial and consumer electronics. The LSSOP package allows for surface mount assembly, facilitating automated manufacturing processes while maintaining high dielectric strength between input and output sides.

Replacement Considerations

RV1S2281ACCSP-10YV-N#KC0 serves as a potential variant within the same family. Verify pinout compatibility before substitution. Ensure replacement parts maintain the 5000 Vrms isolation rating and 15 Mbps speed capability. Cross-reference datasheets for any differences in thermal characteristics or package dimensions.
