FOD817A3S

Overview

The onsemi FOD817A3S is a surface-mount DC input optocoupler featuring a single channel with transistor output. It utilizes MDIP-4 packaging for compact integration. Key electrical parameters include a maximum forward voltage of 1.4V and a maximum input current of 50mA. The device provides an isolation voltage of 5000Vrms, ensuring robust signal transmission across isolated circuits. Typical switching characteristics show rise and fall times of 18μs. The current transfer ratio ranges from a minimum of 80% to a maximum of 160%. Operating temperature spans from -55°C to 110°C, supporting diverse environmental conditions.

Feature Summary

Provides galvanic isolation between input and output circuits using LED-to-transistor technology.
Designed for surface mount installation in compact MDIP-4 packages.
Supports direct DC input signaling without additional conditioning components.

Applications

Signal isolation in industrial control systems
Interface circuits for microprocessor-based logic systems
Power supply feedback loops requiring high isolation

Procurement Notes

Verify the specific suffix 'A3S' against official onsemi documentation to confirm surface-mount MDIP configuration and CTR binning. Ensure compatibility with automated pick-and-place equipment due to the SMD package type. Cross-reference datasheet revision numbers to validate performance specifications against current production standards before finalizing component selection.

Selection Notes

Select this component when surface-mount technology is required for space-constrained designs. The 18μs switching speed suits general-purpose digital isolation rather than high-frequency applications. Verify that the 5000Vrms isolation rating meets safety requirements for the target application's voltage levels. Consider thermal management within the -55°C to 110°C operating range during system design.

Part Context

This part belongs to the FOD817 series, a family of general-purpose optocouplers known for reliability in isolation applications. The FOD817A3S specifically adapts the standard through-hole FOD817A functionality into a surface-mount format. This variant maintains equivalent electrical characteristics while enabling modern PCB assembly techniques, bridging legacy circuit designs with contemporary manufacturing processes.
