FOD2743CSDV

Overview

The FOD2743CSDV is a high-voltage optoisolator manufactured by onsemi, featuring a single channel with a phototransistor output. It provides an insulation voltage of 5000 Vrms and operates within a temperature range of -40°C to +85°C. The device utilizes an SMD-DIP-8 package for surface mount installation. Key electrical parameters include a maximum collector current of 50 mA, a forward voltage of 1.2 V at a forward current of 20 mA, and a collector-emitter saturation voltage of 400 mV. The current transfer ratio ranges from 50% to 100%, with a maximum collector-emitter voltage of 70 V.

Feature Summary

Provides high-voltage isolation capability suitable for demanding industrial environments
Integrates a phototransistor output stage for signal transmission across isolation barriers
Designed for surface mount technology applications requiring compact form factors

Applications

Industrial automation control systems
Power supply feedback loops
Signal isolation in measurement equipment

Procurement Notes

Verify component authenticity through authorized distribution channels due to the part's obsolete status. Confirm that the specific suffix corresponds to the required packaging configuration. Ensure compliance with relevant environmental directives before integration into final assemblies.

Selection Notes

Evaluate the 5000 Vrms isolation rating against system safety requirements. Consider the phototransistor output characteristics for compatibility with downstream logic circuits. Assess thermal management needs within the specified operating temperature range during design validation.

Part Context

This component belongs to the FOD2743 series of optically isolated amplifiers produced by onsemi. The series is designed for error amplifier coupling applications where galvanic isolation is necessary between input and output stages.
