FOD617A

Transistor, Photovoltaic Output Optoisolators Overview

The FOD617A is a single-channel phototransistor optocoupler from the FOD617 Series, manufactured by Fairchild Semiconductor. It features a gallium arsenide infrared emitting diode coupled to a silicon phototransistor in a compact 4-pin package. The device supports surface mount installation and is designed for high operating temperatures up to 110 °C. Key electrical parameters include a minimum collector-emitter breakdown voltage of 70 V, a maximum forward current of 50 mA, and a nominal current transfer ratio of 40%. It offers a maximum insulation voltage of 5000 V and complies with RoHS standards.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., SD) against the datasheet to confirm package type and compliance status. Note that Fairchild Semiconductor has been integrated into ON Semiconductor; check official channels for updated part numbers and availability as legacy stock may be limited or discontinued.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single channel with phototransistor output is required for galvanic isolation. Ensure the application demands a nominal CTR of approximately 40% and can accommodate the specified 5000 Vrms insulation rating. Verify thermal management requirements for operation near the 110 °C upper limit.

Transistor, Photovoltaic Output Optoisolators Part Context

The FOD617A belongs to the FOD617 Series, which includes variants like FOD617B and FOD617A3SD. These devices share similar structural characteristics but differ in current transfer ratio groups and packaging options. The series is designed for applications requiring reliable optical isolation in compact form factors.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Check for direct equivalents within the FOD617 family such as FOD617B for different CTR specifications. Verify compatibility with ON Semiconductor's updated nomenclature if sourcing from post-integration channels.
