FOD2741BV

Overview

The FOD2741BV is a high-voltage optoisolator manufactured by onsemi, classified as an optically isolated amplifier. It features a single channel with a phototransistor output and operates within a temperature range of -40°C to +85°C. The device provides 5000 Vrms insulation voltage and utilizes a PDIP-8 through-hole package. Key electrical parameters include a forward current of 20 mA, a forward voltage of 1.5 V, and a current transfer ratio ranging from 100% to 200%. It supports a maximum collector current of 50 mA, with a maximum collector-emitter saturation voltage of 400 mV and a maximum collector-emitter voltage of 30 V.

Feature Summary

Provides galvanic isolation for error amplifier applications in industrial control systems
Features a phototransistor output stage for signal transmission across isolation barriers
Designed for robust performance in harsh environments with wide operating temperature capabilities

Applications

Industrial process control systems requiring precise error amplification
Power supply feedback loops for voltage regulation
General-purpose isolation in measurement and instrumentation circuits

Procurement Notes

Verify the specific suffix 'BV' against the official datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Check for end-of-life notices or obsolescence warnings prior to finalizing procurement decisions. Ensure compatibility with existing PCB footprints for the PDIP-8 package.

Selection Notes

Select this component when high-voltage isolation is required for linear or error amplifier applications. Consider the 5000 Vrms rating for safety-critical designs. Evaluate the current transfer ratio range to ensure adequate signal margin. Verify that the through-hole mounting style aligns with the assembly process requirements.
