RV1S2281ACCSP-10YC#KC0

Overview

The RV1S2281ACCSP-10YC#KC0 is a transistor output optocoupler from the Renesas RV series, housed in a 4-pin LSSOP surface-mount package. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80 V and a peak forward current rating of 30 mA. The device provides 5000 Vrms isolation voltage and supports a minimum current transfer ratio of 50% up to a maximum of 400%. Key electrical characteristics include a typical rise time of 4 µs, a maximum collector current of 30 mA, and a collector-emitter saturation voltage of 300 mV.

Feature Summary

• Provides high-voltage isolation capability rated at 5000 Vrms for safe signal transmission between circuits.
• Utilizes an NPN phototransistor output stage suitable for digital logic interfacing applications.
• Offers wide current transfer ratio range to accommodate varying input drive conditions.

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission across isolated ground planes
• Digital communication interfaces with noise immunity requirements

Procurement Notes

Verify the specific suffix KC0 against official Renesas documentation to confirm packaging details and safety certifications. Ensure compatibility with LSSOP-4 footprint requirements during PCB layout. Cross-reference UL 1577 and CSA C22.2 No.62368-1 approvals if regulatory compliance is mandatory for the end application.

Selection Notes

Select this component when a compact surface-mount solution with moderate speed (4 µs rise time) and high isolation voltage is required. Consider the 80 V collector-emitter voltage limit and 30 mA output current capability against load requirements. Evaluate the 50-400% current transfer ratio spread to ensure sufficient noise margin under worst-case temperature conditions.

Part Context

This part belongs to the Renesas RV series of optocouplers, designed for general-purpose isolation tasks. The RV1S2281A variant specifically targets applications needing reliable transistor output switching with standard surface-mount integration. It complements other devices in the family by offering a balance of isolation strength and switching performance in a small form factor.

Replacement Considerations

RV1S2281ACCSP-10YC#SC0 is a documented alternative variant within the same product line, differing primarily in packaging or reel specifications rather than core electrical function.
