RV1S2281ACCSP-10YV#SC0

Overview

The RV1S2281ACCSP-10YV#SC0 is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared LED with an NPN silicon phototransistor to provide electrical isolation. The device features a compact LSSOP-4 surface mount package with an 8.2 mm creepage distance, supporting an operating ambient temperature up to 115°C. Key electrical specifications include a maximum collector-emitter voltage of 80 V and a forward current rating of 30 mA. The unit offers a typical rise time of 4 µs and fall time of 5 µs, with a current transfer ratio ranging from 50% to 400%. It complies with UL1577, DIN EN 60747-5-5, and CAN/CSA-C22.2 No.62368-1 standards.

Feature Summary

• High insulation voltage capability of 5000 VRMS for robust signal isolation
• Compact LSSOP-4 package design with extended 8.2 mm creepage distance
• Wide operating temperature range extending to 115°C ambient
• Fast switching performance with microsecond-level rise and fall times

Applications

• Industrial automation control systems requiring galvanic isolation
• Green energy systems and power electronics interfaces
• General-purpose digital signal transmission across isolated barriers
• Microcontroller input/output isolation in embedded applications

Procurement Notes

Verify the complete part number including suffixes such as #SC0 or #KC0, as these indicate specific tape-and-reel packaging configurations rather than functional differences. Confirm that the LSSOP-4 footprint matches your PCB layout constraints. Ensure compliance requirements align with your target market certifications, specifically UL1577 and IEC standards. Check lead times as production cycles may vary based on volume orders.

Selection Notes

Select this component when high isolation voltage and small form factor are critical. The 80 V collector-emitter voltage suits low-voltage logic interfacing. Consider the 30 mA forward current limit for drive circuit design. The NPN phototransistor output requires appropriate pull-up resistor configuration. Verify thermal management needs given the 115°C operating limit.

Part Context

This device belongs to the Renesas RV series of optocouplers, designed for general-purpose isolation applications. The RV1S2281A variant specifically targets cost-sensitive designs requiring reliable DC input to transistor output conversion. The series emphasizes compactness and regulatory compliance for global deployment in industrial and consumer electronics.

Replacement Considerations

Direct substitutes within the same family include RV1S2281ACCSP-10YC#SC0, which shares identical electrical characteristics but differs in reel packaging quantity. Cross-brand replacements require matching 5000 VRMS isolation, 80 V C-E voltage, and LSSOP-4 package dimensions.
