FOD2743BT

Overview

The FOD2743BT is a single-channel optocoupler featuring an integrated error amplifier and NPN phototransistor output, manufactured by onsemi. It provides 5000 Vrms isolation voltage between input and output circuits. The device operates within a temperature range of -40°C to +85°C and is housed in an 8-pin DIP package. Key electrical parameters include a minimum current transfer ratio of 50% at 1 mA input current, a maximum collector-emitter saturation voltage of 400 mV, and a maximum collector-emitter voltage of 70 V. The typical forward voltage is 1.07 V.

Feature Summary

Integrates an error amplifier with a transistor output for precise signal coupling
Provides high-voltage electrical isolation via 5000 Vrms dielectric barrier
Designed for linear applications requiring accurate analog signal transmission

Applications

Power supply feedback loops
Linear optoisolation circuits
Error amplification systems

Procurement Notes

Verify the specific suffix BT against official datasheets to confirm pinout and packaging compatibility. Confirm RoHS compliance status as manufacturing processes may evolve. Check for obsolescence notices or lifecycle changes directly from onsemi documentation before finalizing procurement plans.

Selection Notes

Select this component when high linearity and galvanic isolation are required in power management designs. Ensure the 5000 Vrms rating meets system safety standards. Verify that the NPN output configuration aligns with the downstream circuit requirements and that the operating temperature range covers the intended environment.

Part Context

This part belongs to the FOD2743 series of linear optocouplers. It shares functional similarities with other variants like FOD2743BS and FOD2743BV but differs in packaging and specific mechanical attributes. The series is designed for applications demanding high common-mode transient immunity and stable gain characteristics over temperature variations.
