FOD2743AT

Overview

The onsemi FOD2743AT is a single-channel optoisolator featuring an NPN phototransistor output. It provides a high isolation voltage of 5000Vrms, ensuring robust signal transmission between isolated circuits. The device operates within a temperature range of -40°C to 85°C and utilizes an 8-DIP package for through-hole mounting. Key electrical characteristics include a collector-emitter saturation voltage of up to 400mV and a forward voltage typical value of 1.07V. The component supports a maximum output voltage of 70V and offers a current transfer ratio ranging from 50% to 100% at a 1mA input current.

Feature Summary

Provides galvanic isolation with a 5000Vrms rating for safe signal transmission
Features an NPN phototransistor output for digital switching applications
Designed for surface-mount or through-hole integration in compact designs

Applications

Industrial control systems requiring signal isolation
Power supply feedback loops for error amplification
Microcontroller interface circuits for noise immunity

Procurement Notes

Verify the specific suffix 'AT' against the official datasheet to confirm pinout and packaging details, as variations exist within the FOD2743 family. Confirm RoHS compliance status for your region. Check for end-of-life notices or obsolescence warnings from onsemi before finalizing procurement plans. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when high isolation voltage is required for single-channel applications. Compare the current transfer ratio specifications against your circuit's drive requirements. Consider the thermal operating range limits for your specific environment. Evaluate the package type compatibility with your PCB assembly process. Verify that the output transistor voltage ratings exceed your load requirements.
