FOD2742AV

Overview

The FOD2742AV is an optically isolated amplifier featuring a phototransistor output, manufactured by onsemi. It provides galvanic isolation with a rated voltage of 2500Vrms. The component operates within a temperature range of -25°C to +85°C and is housed in an 8-SOIC surface-mount package. This device is designed for error amplifier applications in power supply circuits.

Feature Summary

Provides high-voltage galvanic isolation between input and output circuits
Integrates a phototransistor output stage for signal transmission
Designed specifically for error amplifier functions in feedback loops

Applications

Power supply error amplification
Feedback loop isolation in switching regulators
Industrial control system signal isolation

Procurement Notes

Verify current availability status as the FOD2742AV is listed as obsolete or end-of-life by the manufacturer. Confirm RoHS compliance details through official datasheets before integration. Check for valid substitute part numbers from onsemi to ensure long-term supply chain stability for production designs.

Selection Notes

Select this component only if legacy design compatibility is required. Evaluate alternative active series parts from onsemi that offer similar isolation ratings and pin configurations. Ensure the 8-SOIC package footprint matches the existing PCB layout constraints without modification.

Part Context

This part belongs to the FOD2742 family of optically isolated amplifiers. It shares functional similarities with variants such as FOD2742BV and FOD2742CV. These devices are engineered for precise analog signal transfer across isolation barriers in industrial and commercial power electronics applications.

Replacement Considerations

Public sources indicate the FOD2742AV is obsolete. Verify specific substitute part numbers from onsemi's current portfolio. Cross-reference pinouts and electrical characteristics to ensure direct replacement feasibility without circuit redesign.
