FOD8802C

Overview

The FOD8802C is a dual-channel transistor output optocoupler from onsemi, housed in an 8-SOIC surface-mount package. It features NPN phototransistor outputs with a collector-emitter voltage of 75 V and a maximum collector current of 30 mA. The device provides 2500 Vrms insulation voltage and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a forward voltage of 1.8 V, a power dissipation of 150 mW, and a reverse voltage of 6 V. Typical switching characteristics show a rise time of 6 µs and a fall time of 7 µs.

Procurement Notes

Verify the specific suffix 'C' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and exact Current Transfer Ratio (CTR) binning requirements. Ensure the procurement source provides valid RoHS compliance documentation consistent with onsemi standards. Cross-reference the Mouser part number 863-FOD8802C for accurate inventory status and lead times before finalizing orders.

Selection Notes

Select this component when dual-channel isolation is required in a compact surface-mount footprint. The 75 V collector-emitter voltage supports standard logic-level interfacing. Verify that the required CTR range aligns with the specific 'C' variant specifications found in the official datasheet. Ensure the PCB layout accommodates the 8-SOIC package dimensions and thermal dissipation needs for the specified power rating.

Part Context

This device belongs to the FOD8802 family of dual-channel optocouplers. It shares core architectural similarities with variants like FOD8802A and FOD8802DR2, differing primarily in packaging format and specific electrical parameter tolerances defined by the suffix. The series leverages onsemi's advanced process technology to deliver reliable signal transmission across isolated boundaries.

Replacement Considerations

Direct substitutes include FOD8802A and FOD8802DR2. Verify pinout compatibility and ensure the replacement variant meets the specific insulation voltage and CTR requirements of the original design. Confirm that the package type matches the existing PCB footprint.
