Overview
The FOD2741CSDV is an optically isolated error amplifier manufactured by onsemi. It integrates a GaAsP infrared LED with an NPN phototransistor output in an SMD-DIP-8 package. Key electrical parameters include a 5000 Vrms isolation voltage, a forward voltage of 1.5 V, and a reference voltage of 2.495 V. The device supports a maximum collector current of 50 mA, a maximum collector-emitter voltage of 30 V, and a power dissipation of 145 mW. It operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a high-efficiency GaAsP infrared LED with an NPN phototransistor for signal transmission.
- Provides robust electrical isolation via a 5000 Vrms insulation voltage rating.
- Includes an internal reference voltage of 2.495 V for precise error amplification applications.
Applications
- Error amplifier circuits in switching power supplies
- Isolated feedback loops in motor drives
- Industrial control systems requiring galvanic isolation
Procurement Notes
Verify the specific suffix 'SDV' against the manufacturer's latest datasheet to confirm pinout and packaging details. Confirm RoHS compliance status through official documentation. Check for end-of-life notices or obsolescence warnings prior to finalizing procurement plans.
Selection Notes
Select this component when high-voltage isolation is required in compact surface-mount designs. Ensure the 30 V collector-emitter voltage and 50 mA current limits meet circuit requirements. Verify that the SMD-DIP-8 footprint aligns with the PCB layout constraints.
Part Context
This part belongs to the FOD2741 series of optically isolated error amplifiers. It shares functional similarities with other variants like FOD2741ASV but differs in packaging and specific manufacturing revisions. The series is designed for applications needing precise analog signal transfer across isolation barriers.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's cross-reference guide for potential alternatives.
