Overview
The FOD8802DR2 is a dual-channel transistor output optocoupler from the OptoHiT series, manufactured by onsemi. It features NPN phototransistor outputs in an 8-pin SOIC package. Key electrical parameters include a maximum collector-emitter voltage of 75 V and a continuous collector current of 30 mA. The device operates with a forward current up to 50 mA and a forward voltage of 1.8 V. Current transfer ratio ranges from 70% to 380%. Insulation voltage is rated at 2500 Vrms. Switching characteristics include a rise time of 6 µs and a fall time of 7 µs. Power dissipation is limited to 150 mW, with an operating temperature range from -40°C to +110°C.
Feature Summary
- Dual-channel configuration within a compact 8-pin Small Outline Integrated Circuit (SOIC) package
- OptoHiT technology providing high current transfer ratio at very low input currents
- High-temperature performance capability for demanding operational environments
- Excellent current transfer ratio linearity maintained across elevated temperatures
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission between isolated circuits
Procurement Notes
Verify the specific suffix DR2 indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the component matches the 8-pin SOIC footprint requirements for your printed circuit board design. Cross-reference the manufacturer part number directly with onsemi records to avoid counterfeit risks.
Selection Notes
Select this component when dual-channel isolation is required in a small form factor. The OptoHiT architecture supports efficient operation at low drive currents, reducing overall system power consumption. Verify that the 75 V collector-emitter voltage rating meets the load requirements. Check that the 2500 Vrms insulation level satisfies safety standards for the intended application environment.
Part Context
This device belongs to the FOD8802A series, which includes variants such as the standard FOD8802A. The FOD8802DR2 specifically denotes the dual-channel version packaged in tape and reel format for automated assembly. It shares core electrical specifications with other members of the OptoHiT family while offering distinct packaging options.
Replacement Considerations
The FOD8802A is a related variant within the same series. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure the replacement part meets the same insulation voltage and temperature ratings.
