Overview
The FOD2741BT is a high-speed optocoupler featuring an internal error amplifier and NPN phototransistor output. It provides 5000 Vrms isolation voltage with a 1.5 V forward voltage drop. The device operates within a -40°C to +85°C temperature range in an 8-pin PDIP package. Key electrical parameters include a maximum collector current of 50 mA, a collector-emitter saturation voltage of 400 mV, and a current transfer ratio ranging from 100% to 200%. It dissipates up to 145 mW and includes a 2.495 V reference voltage for precision applications.
Feature Summary
- Integrates an error amplifier with a phototransistor output for signal conditioning
- Provides robust 5000 Vrms insulation voltage for safety isolation
- Features a wide operating temperature range suitable for industrial environments
Applications
- Error amplifier circuits in power supplies
- Industrial process control systems
- Isolated feedback loops in motor drives
Procurement Notes
Verify the specific suffix 'BT' indicates the tube packaging variant distinct from other tape-and-reel options like 'SDV'. Confirm RoHS compliance status through official datasheets as regulatory requirements evolve. Check for obsolescence notices or lifecycle changes directly from onsemi documentation before finalizing procurement plans.
Selection Notes
Select this component when precise error amplification and high-voltage isolation are required in a single package. Ensure the 100-200% current transfer ratio meets system gain requirements. Verify that the 8-pin DIP footprint fits the target PCB layout constraints compared to surface-mount alternatives.
Part Context
This part belongs to the FOD2741 series of optically isolated amplifiers manufactured by onsemi. It shares functional similarities with variants like FOD2741BV but differs in packaging and supply chain handling. The series is designed for applications requiring reliable galvanic isolation with integrated signal processing capabilities.
Replacement Considerations
Direct substitutes include FOD2741BV (PDIP) and FOD2741ASDV (SMD). Verify pinout compatibility and electrical specifications match exactly. Consider packaging differences when replacing tube-packaged units with reel-packaged equivalents.
