Overview
The FOD2741ATV is a single-channel optically isolated error amplifier manufactured by onsemi. It integrates an infrared LED emitter with an NPN phototransistor output in an 8-pin DIP package. The device provides high isolation voltage of 5000 Vrms and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a forward voltage of 1.5 V, a collector-emitter saturation voltage of 400 mV maximum, and a collector current rating of 50 mA. The unit weight is 720 mg.
Feature Summary
- Integrates an infrared LED with an NPN phototransistor for signal transmission across an insulating barrier.
- Designed specifically as an error amplifier for precision applications requiring galvanic isolation.
- Provides robust electrical isolation between input and output circuits.
Applications
- Precision analog signal isolation in industrial control systems
- Error amplification in isolated power supply feedback loops
- Data acquisition systems requiring high-voltage isolation
Procurement Notes
Verify the specific suffix 'TV' corresponds to the through-hole DIP-8 package variant when sourcing. Confirm RoHS compliance status via the manufacturer's latest documentation. Check for obsolescence notices as this component family may be subject to discontinuation. Ensure the supplier provides valid traceability documents matching the onsemi part number.
Selection Notes
Select this component when a dedicated error amplifier function is required within an optocoupler form factor. The NPN phototransistor output suits linear or switching applications needing moderate current drive. Consider the 5000 Vrms isolation rating for safety-critical designs. Verify that the 8-pin DIP footprint aligns with the target PCB layout constraints.
Part Context
This part belongs to the FOD2741 series of optically isolated amplifiers from onsemi. The series includes variants such as FOD2741ASV and FOD2741BSV, which differ primarily in packaging or minor electrical characteristics. The FOD2741ATV specifically denotes the through-hole DIP configuration within this product line.
Replacement Considerations
Direct substitutes include other parts from the FOD2741 family, such as FOD2741ASV or FOD2741BSV, provided the package type difference is acceptable. Cross-referencing with similar isolated error amplifiers from other manufacturers requires careful verification of pinout compatibility and electrical specifications.
