Overview
The FOD2742CR1V is a single-channel optically isolated amplifier manufactured by onsemi, housed in an 8-SOIC surface-mount package. It integrates an infrared LED with an NPN phototransistor output to provide electrical isolation for signal transmission. Key electrical parameters include a maximum collector-emitter voltage of 70 V and a maximum collector current of 50 mA. The device offers a minimum current transfer ratio of 100% at 10 mA input current, with a typical forward voltage of 1.2 V. It operates within a temperature range of -25°C to +85°C and provides 2500 Vrms insulation voltage.
Feature Summary
- Integrates an error amplifier function within the optocoupler structure for precise signal conditioning
- Provides high-voltage electrical isolation between input and output circuits
- Features a linear response characteristic suitable for analog signal transmission
Applications
- Industrial process control systems requiring isolated feedback loops
- Power supply error amplifier circuits for voltage regulation
- Medical equipment needing galvanic isolation for safety compliance
Procurement Notes
Verify component authenticity through authorized distributors as this part is obsolete. Check for RoHS compliance status in official documentation. Confirm pinout compatibility if replacing existing designs. Review datasheet revisions for any parameter updates before finalizing procurement specifications.
Selection Notes
Select this component when linear isolation with integrated amplification is required. Ensure the 70 V collector-emitter voltage rating meets circuit requirements. Verify that the 8-SOIC package dimensions fit the PCB layout constraints. Consider thermal dissipation limits given the 145 mW power dissipation specification during operation.
Part Context
This device belongs to the FOD2742 series of optically isolated amplifiers from onsemi. It is designed for applications requiring both isolation and signal amplification in a compact form factor. The series includes variants with different packaging and tape/reel options for automated assembly processes.
Replacement Considerations
FOD2742BR2V is listed as a similar replacement option available from onsemi. Verify functional equivalence and pin compatibility before substitution. Check availability status as the original part is obsolete.
