Overview
The FOD250LS is a photovoltaic output optoisolator manufactured by onsemi. It features a single channel with 5000Vrms isolation voltage and an 8-SMD package. The device utilizes a transistor output with base configuration. Key electrical parameters include a minimum current transfer ratio of 15% at 16mA input current and a maximum current transfer ratio of 50%. This component is designed for signal isolation applications requiring high voltage blocking capabilities.
Feature Summary
- Provides galvanic isolation between input and output circuits
- Features photovoltaic output architecture with integrated base connection
- Supports high voltage isolation ratings for safety compliance
Applications
- Industrial communication interface isolation
- Microcontroller I/O isolation in noisy environments
- Power supply feedback loop isolation
Procurement Notes
Verify product status carefully as the FOD250LS is listed as obsolete and no longer manufactured by onsemi. Sourcing may be limited to existing stock or secondary markets. Ensure compatibility with replacement components such as the 6N135-300E if availability is critical. Confirm package type and pinout alignment before procurement to avoid integration issues.
Selection Notes
Select this component only if legacy system compatibility requires the specific photovoltaic output topology. Consider the obsolete status when designing new products, as long-term supply assurance is not guaranteed. Evaluate alternative modern optoisolators with similar isolation voltages and CTR specifications for new designs to ensure manufacturing continuity.
Part Context
The FOD250LS belongs to onsemi's portfolio of transistor output optoisolators. It is part of a broader category of devices used for electrical isolation in electronic systems. The manufacturer specializes in intelligent power and sensing technologies, providing solutions for industrial, automotive, and consumer applications. This specific model represents an older generation of isolation technology.
Replacement Considerations
The 6N135-300E from Broadcom Limited is identified as a similar substitute part number. Verify functional equivalence regarding isolation voltage and current transfer ratio before substitution.
