FOD617ASD

Overview

The FOD617ASD is a single-channel transistor output optocoupler manufactured by Fairchild Semiconductor, now part of ON Semiconductor. It features an NPN phototransistor output and provides 5000 Vrms isolation voltage. The device is housed in a 4-SMD Gull Wing package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a typical rise/fall time of 4 µs/3 µs, and a forward current rating of 50 mA. The component is RoHS compliant and lead-free.

Feature Summary

• Provides high-voltage isolation between input and output circuits
• Utilizes an NPN phototransistor for signal transmission
• Designed for surface-mount assembly applications

Applications

• General-purpose signal isolation
• Industrial control systems
• Consumer electronics interface circuits

Procurement Notes

Verify the manufacturer status carefully as this component is listed as obsolete or discontinued by Fairchild Semiconductor. Due to the integration with ON Semiconductor, check for updated part number nomenclature where underscores may be replaced by dashes. Confirm availability through authorized distributors or alternative sources, as original stock is limited. Ensure the specific package variant matches the design requirements.

Selection Notes

Select this component only if surface-mount packaging is required for the application. Consider the obsolete status when planning long-term production runs. Verify that the 5000 Vrms isolation rating meets safety standards. Evaluate alternative active components from the same manufacturer family if supply continuity is critical for future manufacturing phases.

Part Context

This device belongs to the FOD617 series of transistor output optocouplers. The series is characterized by high isolation voltage and standard phototransistor outputs. Fairchild Semiconductor has been integrated into ON Semiconductor, affecting part numbering and production status. This specific model represents a surface-mount version within that broader product line.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material. Users should consult ON Semiconductor catalogs for equivalent active devices or verify cross-reference data with authorized distributors.
