FOD8802CR2

Overview

The FOD8802CR2 is a dual-channel transistor output optocoupler from onsemi, housed in an 8-pin SOIC package. It features NPN phototransistor outputs with a maximum collector-emitter voltage of 75 V and a collector current of 30 mA. The device provides an insulation voltage of 2500 Vrms and operates within a temperature range of -40°C to +110°C. Key electrical parameters include a forward current of 50 mA, forward voltage of 1.8 V, and power dissipation of 150 mW. Propagation delays are specified at 6 µs rise time and 7 µs fall time, with a current transfer ratio ranging from 70% to 380%.

Feature Summary

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

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission between isolated circuits

Procurement Notes

Verify the specific suffix 'CR2' against the manufacturer's latest datasheet to confirm packaging details such as reel or cut tape specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering part number with official distributor catalogs to avoid confusion with similar series variants like FOD8802DR2. Confirm lead times and availability directly with authorized suppliers before finalizing procurement plans.

Selection Notes

Select this component when dual-channel isolation is required within a compact SOIC-8 footprint. Consider the 75 V collector-emitter voltage rating for low-voltage signal switching applications. Evaluate the 2500 Vrms insulation rating against system safety standards. Compare propagation delays and CTR ranges with alternative devices if higher speed or tighter gain tolerances are necessary for the specific circuit design.

Part Context

This part belongs to the FOD8802A series of transistor output optocouplers manufactured by onsemi. It utilizes proprietary process technology to deliver high performance in a standard surface-mount package. The series is designed for general-purpose isolation tasks where moderate speed and reliable signal transmission are prioritized over high-speed digital communication capabilities.

Replacement Considerations

Check for direct pin-compatible substitutes within the same family, such as FOD8802DR2, ensuring identical channel count and output type. Verify that any replacement maintains the same 75 V Vceo and 2500 Vrms isolation ratings. Confirm that the alternative device's current transfer ratio and propagation delay specifications meet the original design constraints.
