FODM121EV

Overview

The FODM121EV is a single-channel optoisolator featuring a phototransistor output, manufactured by onsemi. It provides an isolation voltage of 3750Vrms and operates within a temperature range of -40°C to 110°C. The device utilizes a DC input type and offers a typical rise/fall time of 3µs. Key electrical parameters include a maximum collector-emitter saturation voltage of 400mV, a forward current of up to 50mA, and a current transfer ratio ranging from 100% to 300% at 5mA input. It is housed in a 4-SMD,鸥翼 (gull-wing) package.

Feature Summary

Provides high-voltage galvanic isolation between input and output circuits
Features a phototransistor output for digital signal transmission
Designed for surface-mount assembly with a compact footprint

Applications

Industrial control systems requiring signal isolation
Consumer electronics with safety isolation requirements
Power supply feedback loops

Procurement Notes

Verify the specific suffix 'EV' against the manufacturer's latest datasheet to confirm it denotes the tape-and-reel packaging variant or a specific environmental compliance status distinct from the standard 'AR2V' version. Ensure the component matches the required RoHS and REACH declarations as specified in the official documentation before finalizing procurement orders.

Selection Notes

Select this component when a single-channel transistor output isolator is needed with a 3750Vrms isolation rating. Consider the 3µs switching speed for moderate-speed applications. Verify that the 4-SMD gull-wing package fits the PCB layout constraints and that the operating temperature range meets the system's thermal requirements.

Part Context

This part belongs to onsemi's standard product line of optoisolators. It is part of the FODM121 family, which includes variants like FODM121A and FODM121AR2V. These devices are designed for general-purpose isolation tasks in industrial and consumer markets, offering reliable performance in compact packages.
