Overview
The FOD2741ASD is a single-channel optically isolated error amplifier manufactured by onsemi. It integrates a precision programmable shunt reference with an NPN phototransistor output in an 8-SMD package. Key electrical parameters include a maximum collector-emitter voltage of 30 V, a forward voltage of 1.5 V, and a current transfer ratio ranging from 100% to 200% at 10 mA input. The device offers 5000 Vrms insulation voltage and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a precision programmable shunt reference with an optocoupler for compact error amplification
- Provides high-voltage electrical isolation between input and output circuits
- Features an NPN phototransistor output stage for signal transmission
Applications
- Switch-mode power supply feedback loops
- Battery management systems
- Industrial control circuit isolation
Procurement Notes
Verify the specific suffix designation against the manufacturer's official datasheet to confirm pinout compatibility and packaging type. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding assembly or material updates before finalizing procurement specifications.
Selection Notes
Select this component when a combined error amplifier and isolation barrier are required in a single package. Ensure the design accommodates the 30 V collector-emitter voltage limit and the specific current transfer ratio characteristics. Verify that the 8-SMD footprint matches the target PCB layout constraints.
Part Context
This part belongs to the FOD2741 series of optically isolated amplifiers. It serves as a specialized solution for applications requiring both precise voltage referencing and galvanic isolation, distinguishing it from standard discrete optocouplers or standalone voltage references.
Replacement Considerations
Check for direct substitutes within the FOD2741 family, such as FOD2741AS or FOD2741BSDV, ensuring pin compatibility and identical electrical ratings are maintained for the specific application requirements.
