FOD2743BSDV

Overview

The FOD2743BSDV is a surface-mount optically isolated amplifier manufactured by onsemi. It integrates an error amplifier with a phototransistor output in an 8-SMD package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a typical forward voltage of 1.07 V, and a maximum saturation voltage of 400 mV. The device operates within a temperature range of -40°C to +85°C and provides 5000 Vrms isolation. Power dissipation is rated at 145 mW.

Feature Summary

Integrates an error amplifier with a phototransistor output for signal isolation
Provides high-voltage insulation capability between input and output circuits
Designed for surface-mount assembly in compact electronic systems

Applications

Error amplifier coupling in power supply feedback loops
Isolated signal transmission in industrial control systems
Voltage regulation circuits requiring galvanic isolation

Procurement Notes

Verify the specific suffix 'BSDV' against official datasheets to confirm package type and tape-and-reel specifications. Confirm current production status as some variants in this series may be obsolete. Ensure compatibility with existing PCB footprints and reflow soldering profiles before procurement.

Selection Notes

Select this component when an integrated error amplifier with optical isolation is required. Compare the 70 V collector-emitter voltage and 145 mW power dissipation against circuit requirements. Verify that the 8-SMD form factor fits the design constraints and that the operating temperature range meets environmental conditions.

Part Context

This part belongs to the FOD2743 family of optically isolated amplifiers from onsemi. The family includes variants such as FOD2743CS and FOD2743BSD, which share similar functional architectures but differ in packaging and availability status. These devices are designed for applications requiring precise analog signal transfer across isolation barriers.
