FOD2743CSD

Overview

The FOD2743CSD is a transistor output optocoupler designed as an error amplifier coupler. It features a single channel with a phototransistor output. Key electrical parameters include a collector-emitter breakdown voltage of 70 V, a maximum forward current of 20 mA, and a nominal forward voltage of 1.2 V. The device offers a high isolation voltage of 5000 Vrms. The current transfer ratio ranges from 50% to 100%. It operates within a temperature range of -40°C to +85°C and is housed in an SMD-DIP-8 package.

Feature Summary

Integrated error amplifier coupling functionality for precision signal transmission
High insulation voltage capability ensuring robust circuit isolation
Wide operating temperature range suitable for diverse environmental conditions

Applications

Switching power supply feedback loops
Industrial control system isolation
Signal transmission between isolated circuits

Procurement Notes

Verify the specific suffix CSD against the manufacturer's latest documentation to confirm pinout and packaging details. Check for obsolescence status as onsemi may have discontinued this specific variant. Ensure compliance with RoHS directives if required by the target application. Confirm availability through authorized distributors due to potential lifecycle changes.

Selection Notes

Select this component when high isolation voltage and error amplifier integration are required. Compare the 5000 Vrms isolation rating against system safety standards. Evaluate the 70 V collector-emitter voltage against load requirements. Consider the SMD-DIP-8 package for PCB layout constraints. Verify the current transfer ratio specifications match the driving circuit capabilities.

Part Context

The FOD2743 series includes variants like FOD2743BTV and FOD2743CS. These devices belong to the optically isolated amplifier category. Fairchild Semiconductor originally developed this line, which is now managed by onsemi. The series provides transistor output options for various isolation needs.

Replacement Considerations

Check for direct substitutes such as FOD2743BS or other series members. Verify pin compatibility and electrical parameter equivalence before substitution.
