Overview
The RV1S2951ACCNS-1F0C#SC0 is a high-speed optocoupler manufactured by Renesas Electronics Corporation. It features a GaAsP LED coupled to a high-speed photodiode array receiver, providing a propagation delay of 3 ns and a pulse width distortion of 1 ns. The device supports data rates up to 50 Mbps and operates with a supply voltage range of 4.5 V to 5.5 V on the input side and 3.0 V to 5.5 V on the output side. It offers a minimum common-mode transient immunity of 50 kV/µs and an isolation voltage of 5000 Vrms. Packaged in a narrow SOIC-8 (NS) format, it functions within an ambient temperature range of -40 °C to +125 °C.
Feature Summary
- High-speed signal transmission capability supporting data rates up to 50 Mbps
- Robust noise immunity characterized by a minimum common-mode transient immunity of 50 kV/µs
- Integrated high-voltage isolation barrier rated at 5000 Vrms for safe circuit separation
- Wide operating temperature range extending from -40 °C to +125 °C
Applications
- Industrial communication interfaces requiring galvanic isolation
- Isolated gate driver circuits for power electronics
- Data acquisition systems with high noise environments
- Medical equipment requiring reinforced insulation barriers
Procurement Notes
Verify the specific suffix SC0 against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and check for lead-free status as indicated in current datasheets. Confirm availability through authorized distributors, as stock levels fluctuate. Validate that the component meets the required safety certifications such as UL or VDE for your specific application region.
Selection Notes
Select this component when high-speed digital isolation is critical for system performance. The 50 Mbps rate suits applications where standard optocouplers are too slow. Consider the narrow SOIC-8 package for space-constrained PCB layouts. Verify that the input current requirements align with your driving logic levels and that the output voltage swing matches the receiving device thresholds.
Part Context
This part belongs to the RV1S29xx series of high-speed optocouplers from Renesas. These devices utilize advanced GaAsP technology to achieve superior speed and reliability compared to traditional silicon phototransistor optocouplers. The series is designed for demanding industrial and automotive applications where signal integrity and isolation strength are paramount.
Replacement Considerations
Consult official Renesas cross-reference guides for verified substitutes. Generic replacements may not match the 50 kV/µs CMTI or 50 Mbps speed. Ensure any alternative maintains the same pinout and isolation voltage ratings to avoid redesigning the isolation barrier.
