Overview
The FOD2741ASDV is a single-channel optically isolated amplifier manufactured by onsemi, designed for precision applications requiring high-voltage isolation. It integrates an error amplifier and a reference voltage source within a compact SMD-DIP-8 package. The device features a phototransistor output with a current transfer ratio ranging from 100% to 200%. Key electrical parameters include a maximum collector current of 50 mA, a maximum collector-emitter saturation voltage of 400 mV, and a maximum collector-emitter voltage of 30 V. The forward voltage is specified at 1.5 V, while the power dissipation capability is 145 mW. It operates within a temperature range of -40°C to +85°C and provides 5000 Vrms insulation.
Feature Summary
- Integrates a precision reference voltage source and error amplifier in a single package
- Provides high common-mode transient immunity for reliable signal transmission
- Features a phototransistor output suitable for linear and switching applications
Applications
- Industrial control systems requiring galvanic isolation
- Commercial power supply feedback loops
- Consumer electronics with high-voltage safety requirements
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging variants such as reel, cut tape, or MouseReel options based on production needs. Ensure the part number suffix matches the required tape and reel configuration. Review recent Product Change Notifications for any assembly or material updates that may affect integration.
Selection Notes
Select this component when precise voltage referencing and error amplification are needed alongside optical isolation. The integrated 2.495 V reference simplifies circuit design compared to discrete solutions. Consider the 8-SMD gull-wing package for surface-mount assembly constraints. Evaluate the 100% to 200% current transfer ratio against system gain requirements. Ensure the operating temperature range aligns with the environmental conditions of the target application.
Part Context
This device belongs to the FOD2741A series of optocouplers. It is distinct from other variants like the FOD2741BSV primarily by its packaging format, which is optimized for surface-mount technology. The series is characterized by its combination of analog signal processing capabilities with robust isolation barriers, catering to applications demanding both accuracy and safety.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing board layouts if considering alternative models from the same family.
