FOD2741BS

Overview

The FOD2741BS is a single-channel optically isolated amplifier manufactured by onsemi. It integrates an infrared LED with an NPN phototransistor output and an internal error amplifier featuring a 2.495 V reference voltage. The device provides 5000 Vrms insulation and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum collector current of 50 mA, a forward voltage of 1.5 V, and a power dissipation of 145 mW. It is housed in an SMD-DIP-8 package.

Feature Summary

Integrates an error amplifier with a fixed internal reference voltage for linear signal isolation
Provides high-voltage galvanic isolation between input and output circuits
Utilizes an NPN phototransistor output stage for driving external loads

Applications

Error amplifier applications in isolated power supply feedback loops
Linear isolation of analog control signals in industrial systems
Voltage regulation circuits requiring galvanic separation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package type. Check for obsolescence notices as this series may be discontinued. Ensure compliance with RoHS directives if applicable to the target market. Validate datasheet revisions against the specific lot code received.

Selection Notes

Select this component when linear isolation with integrated amplification is required. Compare current transfer ratio specifications against load requirements. Verify that the operating temperature range meets environmental conditions. Ensure the isolation voltage rating exceeds the system's peak transient voltages. Consider pin compatibility with existing PCB footprints.

Part Context

This part belongs to the FOD2741B family of optocouplers designed for precision analog isolation. It differs from standard digital optocouplers by including an internal amplifier circuit. The family typically includes variants with different packaging options such as through-hole and surface mount configurations.
