Overview
The FOD2712A is a single-channel optically isolated error amplifier manufactured by onsemi. It integrates an infrared LED with an NPN phototransistor output in an 8-pin SOIC package. Key electrical parameters include a 2500 Vrms isolation voltage, a typical current transfer ratio of 100%, and a maximum collector current of 50 mA. The device operates within a temperature range of -40°C to +85°C and features a forward voltage of 1.5 V.
Feature Summary
- Integrates an infrared emitter with an NPN phototransistor for signal transmission
- Provides high-voltage electrical isolation between input and output circuits
- Designed specifically for use as an isolated error amplifier in feedback loops
Applications
- Switch-mode power supply feedback control
- Isolated voltage regulation systems
- Industrial motor drive control circuits
Procurement Notes
Verify the specific suffix (e.g., 'R2' for reel packaging) against the required delivery format. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the selected variant matches the intended thermal and mechanical constraints of the final assembly design.
Selection Notes
Select this component when precise analog isolation is required for error signal transmission. Consider the 100% CTR and 50 mA output capability for driving subsequent stages. Evaluate the SOIC-8 footprint compatibility and ensure the operating temperature range meets the environmental requirements of the target application.
Part Context
This part belongs to the FOD2712 series of optically isolated amplifiers from onsemi. These devices are engineered to replace traditional transformer-based isolation methods in precision applications. The series offers a compact solution for maintaining signal integrity across galvanic barriers in sensitive electronic designs.
Replacement Considerations
The FOD2712AR2 is a direct functional equivalent differing primarily in tape-and-reel packaging. Verify pinout compatibility and electrical specifications before substituting with other isolated amplifier models.
