FOD2741B

Overview

The FOD2741B is a single-channel optically isolated amplifier manufactured by onsemi, designed for precision error amplification in power conversion systems. It integrates an infrared LED with an NPN phototransistor output and a built-in reference voltage of 2.495 V. The device provides high isolation capability of 5000 Vrms and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum collector-emitter voltage of 30 V, a current transfer ratio of 100% at 10 mA input, and a maximum forward voltage of 1.5 V. It is housed in an 8-pin PDIP package.

Feature Summary

Integrates a precision internal reference voltage for accurate error signal processing
Provides galvanic isolation between input control circuits and high-voltage outputs
Combines linear amplifier functionality with optical transmission for noise immunity

Applications

Switching power supply feedback loops
Motor drive control circuits
Industrial process control systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolescence status. Confirm lot traceability and RoHS compliance documentation prior to integration. Validate that the specific revision matches design requirements as end-of-life products may have limited long-term availability support.

Selection Notes

Select this component when precise voltage referencing and high isolation are required in compact form factors. Ensure input current limits do not exceed specifications to maintain linearity. Consider thermal dissipation capabilities within the PDIP package for continuous operation under load conditions.

Part Context

Part of the FOD2741 series, which includes variants like FOD2741A and FOD2741C offering different current transfer ratios. This series addresses applications needing reliable isolation with integrated reference voltages, simplifying circuit design compared to discrete solutions.
