Overview
The RV1S2251ACCSP-10YV#KC0 is a transistor output optocoupler manufactured by Renesas Electronics. It features a single channel with an AlGaAs LED input and an NPN silicon phototransistor output housed in an LSSOP-4 package. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a maximum collector current of 40 mA, and an isolation voltage of 5000 Vrms. The device supports a forward current of 30 mA with a forward voltage of 1.15 V. The current transfer ratio ranges from 200% to 400%.
Feature Summary
- Provides high-speed signal transmission via an AlGaAs LED and NPN phototransistor configuration.
- Offers robust electrical isolation with a 5000 Vrms insulation voltage rating.
- Delivers high current transfer efficiency within the specified operating range.
Applications
- General-purpose signal isolation in industrial control systems.
- Interface circuits for microcontrollers requiring galvanic separation.
- Power supply feedback loops for noise immunity.
Procurement Notes
Verify the specific suffix KC0 against official Renesas documentation to confirm pinout and material composition. Ensure compatibility with LSSOP-4 footprint requirements during PCB layout. Confirm that the 5000 Vrms isolation rating meets the safety standards required for your specific application environment. Cross-reference the RoHS status with the latest manufacturer declaration before procurement.
Selection Notes
Select this component when a compact LSSOP-4 package is required for space-constrained designs. Choose this part if the application demands a minimum current transfer ratio of 200% for reliable switching. Ensure the system operates within the 30 mA forward current limit and 40 V collector-emitter voltage constraints. Verify that the NPN output type aligns with the downstream circuit logic requirements.
Part Context
This component belongs to the RV1S series of optocouplers from Renesas Electronics. The series is designed for general-purpose isolation applications. The RV1S2251A variant specifically utilizes an AlGaAs LED for efficient light emission. The LSSOP-4 package provides a small form factor suitable for surface mount assembly processes.
Replacement Considerations
Consult official Renesas substitution guides for verified equivalents. Generic replacements may not match the specific 200-400% current transfer ratio or 5000 Vrms isolation rating. Verify pin compatibility and package dimensions before substituting.
