Overview
The FOD2741BSD is a single-channel optically isolated error amplifier manufactured by onsemi. It integrates an infrared LED with a phototransistor output in an 8-SMD package. Key electrical parameters include a 5000 Vrms isolation voltage, a forward current of 20 mA, and a forward voltage of 1.5 V. The device features a current transfer ratio ranging from 100% to 200%, a maximum collector current of 50 mA, and a reference voltage of 2.495 V. It operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates an error amplifier function for precise signal isolation
- Provides high-voltage galvanic isolation between input and output circuits
- Utilizes a phototransistor output stage for digital or analog switching applications
Applications
- Error amplifier circuits in power supply feedback loops
- Isolated signal transmission in industrial control systems
- Voltage regulation monitoring in switching mode power supplies
Procurement Notes
Verify component authenticity through authorized distributors due to the presence of obsolete variants in the FOD2741 series. Confirm that the specific suffix 'BSD' corresponds to the surface-mount 8-SMD package variant rather than through-hole versions. Check for RoHS compliance documentation as manufacturing processes may vary across production lots. Ensure the supplier provides valid traceability records for quality assurance purposes.
Selection Notes
Select this component when a dedicated error amplifier function is required within an isolated environment. The integrated reference voltage simplifies circuit design compared to discrete optocouplers. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the 100-200% current transfer ratio to ensure adequate gain for the specific application requirements without excessive drive current.
Part Context
This part belongs to the FOD2741B series of optically isolated amplifiers. It shares functional similarities with other members like the FOD2741ASDV but differs in packaging and specific electrical tolerances. The series is designed for applications requiring reliable isolation with built-in amplification capabilities, distinguishing it from standard logic-level optocouplers.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative models such as the FOD2741ASDV only if pinout and electrical specifications match exactly.
