FOD2742BR2

Overview

The FOD2742BR2 is a high-speed optically isolated amplifier manufactured by onsemi, designed for precision analog signal transmission across isolation barriers. It integrates an infrared LED with a specialized photodetector and output stage to provide linear response characteristics. The device operates within a temperature range of -25°C to +85°C and utilizes an 8-SOIC surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 70V, a typical forward voltage of 1.2V, and a power dissipation rating of 145mW. It offers a minimum current transfer ratio of 100% at 10mA input.

Feature Summary

Provides high-speed linear isolation for accurate analog signal transmission between circuits.
Integrates an error amplifier architecture to maintain signal fidelity across the isolation barrier.
Features a compact 8-SOIC surface-mount package suitable for automated assembly processes.

Applications

Precision analog signal isolation in industrial control systems
Error amplifier circuits in switching power supplies
Isolated feedback loops in motor drive applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging variants such as tape-and-reel options. Review the latest datasheet revision history for any design changes or pinout updates before finalizing procurement specifications.

Selection Notes

Select this component when high linearity and speed are required for isolated analog signals. Ensure the operating temperature range meets system requirements. Verify that the 70V output voltage rating and 50mA output current capability align with the load requirements of the target application circuit.

Part Context

This part belongs to the FOD2742B series of optically isolated amplifiers from onsemi. It is distinct from standard digital optocouplers by its linear transfer characteristic, making it suitable for applications requiring precise voltage or current replication across isolation boundaries rather than simple logic state transmission.

Replacement Considerations

Consult official substitution guides for compatible alternatives within the same family. Verify pin compatibility and electrical parameter equivalence before replacing. Cross-reference with similar high-speed linear optocouplers if exact matches are unavailable.
