FOD2712R1

Overview

The FOD2712R1 is a single-channel optically isolated amplifier manufactured by onsemi. It integrates an infrared LED with an NPN phototransistor output in an 8-SOIC package. The device provides 2500 Vrms insulation voltage and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a forward current of 20 mA, a forward voltage of 1.5 V, and a collector-emitter saturation voltage of 400 mV maximum. The current transfer ratio ranges from 100% to 200%, with a maximum collector current of 50 mA and a maximum collector-emitter voltage of 30 V.

Feature Summary

Integrates an error amplifier function for precise signal isolation
Provides high-voltage galvanic isolation between input and output circuits
Features a compact surface-mount SOIC-8 package design

Applications

Isolated error amplification in switching power supplies
Feedback loop isolation in motor control systems
Signal transmission across ground potential differences in industrial equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix R1 matches project requirements, as packaging variants exist. Check current lifecycle status, as this model may be obsolete or subject to supply constraints. Ensure RoHS compliance documentation aligns with regulatory needs for the target market.

Selection Notes

Select this component when a dedicated isolated error amplifier is required rather than a standard digital optocoupler. Consider the 2500 Vrms isolation rating for safety compliance. Evaluate the 100-200% current transfer ratio for gain stability. Compare against the FOD2712A if tube packaging is preferred over reel or cut tape formats.

Part Context

This part belongs to the FOD2712 series of optically isolated amplifiers from onsemi. These devices are designed to replace traditional transformer-coupled feedback loops. The series offers enhanced linearity and bandwidth compared to basic logic optocouplers, making them suitable for linear analog signal transmission across isolation barriers.
