FOD8802D

Overview

The FOD8802D is a dual-channel transistor output optocoupler from onsemi, housed in an 8-pin SOIC package. It provides electrical isolation with a rated insulation voltage of 2500 Vrms. The device features NPN phototransistor outputs capable of handling a maximum collector current of 30 mA and a collector-emitter voltage of 75 V. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.8 V, and a reverse voltage rating of 6 V. The unit supports a power dissipation of 150 mW and operates within a temperature range of -40°C to +110°C.

Feature Summary

• Dual-channel configuration for independent signal isolation
• High insulation voltage capability for safety separation
• NPN phototransistor output structure

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission across isolated grounds

Procurement Notes

Verify the specific suffix 'D' corresponds to the tube packaging format rather than tape-and-reel variants like 'DR2'. Confirm RoHS compliance status through official documentation. Ensure the procurement order matches the exact manufacturer part number to avoid confusion with similar series components such as the FOD8802A which may have different current transfer ratio specifications.

Selection Notes

Select this component when dual-channel isolation is required within a compact surface-mount footprint. Consider the 2500 Vrms insulation rating for applications demanding robust safety barriers. Evaluate the 75 V collector-emitter voltage limit against the load requirements. The wide operating temperature range makes it suitable for harsh industrial environments where thermal stability is critical for reliable signal transmission.

Part Context

This component belongs to the FOD8802 family of high-speed optocouplers designed for general-purpose isolation tasks. It shares architectural similarities with other members like the FOD8802A but differs in packaging and specific electrical tolerances. The series is characterized by fast switching times and high current transfer ratios, positioning it as a standard solution for bridging low-voltage logic circuits with higher voltage loads in diverse electronic designs.
