FOD2741BTV

Overview

The FOD2741BTV is a single-channel optically isolated amplifier featuring an NPN phototransistor output, manufactured by onsemi. It operates within a temperature range of -40°C to +85°C and utilizes a PDIP-8 through-hole package. Key electrical specifications include a maximum collector-emitter voltage of 30 V, a forward voltage of 1.5 V, and a power dissipation of 145 mW. The device provides 5000 Vrms insulation voltage and maintains a reference voltage of 2.495 V.

Feature Summary

Integrates an error amplifier with optical isolation for signal transmission
Provides high-voltage isolation between input and output circuits
Features a transistor output stage for digital or analog switching applications

Applications

Error amplifier circuits in power supply feedback loops
Isolated signal transmission in industrial control systems
Voltage regulation monitoring in switching power converters

Procurement Notes

Verify the specific suffix 'TV' to confirm the tape-and-reel packaging format, as this differs from bulk tube variants like the standard B version. Confirm current lifecycle status, as documentation indicates potential obsolescence or not recommended for new designs (NRND) status for certain revisions. Ensure compatibility with existing PCB footprints for the 8-pin DIP configuration before procurement.

Selection Notes

Select this component when a dedicated error amplifier function with galvanic isolation is required in a through-hole design. Compare the 30 V collector-emitter voltage limit against system requirements; higher voltage variants such as the FOD2743 series may be necessary if operating voltages exceed 30 V. Consider the 1.5 V forward voltage drop for LED drive circuit calculations.

Part Context

This part belongs to the FOD2741 family of optically isolated amplifiers. It shares functional similarities with the FOD2741B but differs in packaging and distribution format. The TV suffix typically denotes a reel-based packaging option suitable for automated assembly processes, distinguishing it from manual insertion variants.
