Overview
The RV1S2251ACCSP-10YC#KC0 is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an LSSOP-4 surface-mount package and provides 5000 Vrms isolation voltage. The device utilizes an NPN phototransistor output with a maximum collector-emitter voltage of 80 V and a maximum collector current of 30 mA. Key electrical parameters include a forward current of 30 mA, a forward voltage of 1.4 V, and a collector-emitter saturation voltage of 300 mV. The current transfer ratio ranges from 50% to 400%, with a rise time of 4 µs.
Feature Summary
- Provides high-voltage galvanic isolation between input and output circuits
- Features a compact surface-mount LSSOP-4 package for automated assembly
- Utilizes an NPN phototransistor output stage for digital signal transmission
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix #KC0 against official Renesas documentation to confirm packaging details and compliance status. Ensure the component matches the required isolation voltage and package type for your design. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and availability. Check for any recent product change notices that may affect specifications or lead times.
Selection Notes
Select this component when a single-channel transistor output isolator with 5000 Vrms isolation is required in an LSSOP-4 package. Consider the 80 V collector-emitter voltage and 30 mA output current limits for load compatibility. Evaluate the 4 µs rise time against system speed requirements. Compare against other RV series devices if higher data rates or different output types are needed.
Part Context
This part belongs to the Renesas RV series of optocouplers, which are designed for general-purpose isolation applications. The series includes various packages and output types to suit different industrial and consumer electronics needs. The RV1S2251A variant specifically targets applications requiring robust isolation in a small form factor.
Replacement Considerations
Consult official Renesas substitution guides for verified alternatives. Generic equivalents may not match the specific isolation voltage or package dimensions.
