FOD8802AR2

Overview

The FOD8802AR2 is a dual-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output with a minimum current transfer ratio of 70% and a maximum of 380%. The device supports a forward current of 50 mA and a collector-emitter voltage of 75 V. Key electrical parameters include a rise time of 6 µs, a fall time of 7 µs, and a power dissipation of 150 mW. It operates within a temperature range of -40°C to +110°C and provides 2500 Vrms insulation voltage.

Feature Summary

• Dual-channel configuration for independent signal isolation
• High current transfer ratio for efficient switching
• Wide operating temperature range for industrial environments

Applications

• Industrial process control systems
• Power supply feedback loops
• Signal isolation in communication interfaces

Procurement Notes

Verify the specific suffix AR2 indicates tape and reel packaging containing 2500 units per reel. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required package type and quantity constraints defined by the supplier.

Selection Notes

Select this component when dual-channel isolation with high CTR is required. Compare against single-channel alternatives if space is limited. Verify that the 75V output voltage rating meets the circuit requirements. Check thermal management needs given the 150mW power dissipation limit.

Part Context

This part belongs to the FOD8802 family of Optohit™ phototransistor optocouplers. It utilizes onsemi's proprietary工艺技术 for reliable performance. The series includes variants like FOD8802A and FOD8802DR2, differing primarily in packaging and specific electrical tolerances.

Replacement Considerations

FOD8802A is a related variant with different CTR specifications (65%-150%). FOD8802DR2 shares similar electrical characteristics but may differ in packaging or batch specifications. Verify pinout compatibility before substitution.
