FODM214A

Overview

The FODM214A is a single-channel phototransistor optocoupler designed for AC/DC sensing input applications. It features an NPN phototransistor output housed in a compact MFP-4 surface-mount package. The device provides an insulation voltage of 3750 Vrms, ensuring robust isolation between input and output circuits. Key electrical parameters include a minimum current transfer ratio of 50% and a maximum of 250%. The forward current rating is 50 mA with a forward voltage of 1.4 V. The collector-emitter voltage withstands up to 80 V, while the maximum collector current is 50 mA. Saturation voltage is limited to 400 mV, and switching times are characterized by rise and fall times of 3 µs each.

Feature Summary

Single-channel configuration optimized for AC/DC sensing inputs
High insulation voltage capability for circuit isolation
Compact MFP-4 surface-mount package design
NPN phototransistor output structure

Applications

AC/DC sensing input circuits
General purpose signal isolation
Industrial control systems

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as distribution channels may list different tape-and-reel or cut-tape options under the same base part number. Confirm RoHS compliance status and manufacturer documentation availability directly from onsemi authorized distributors to ensure component authenticity and traceability prior to purchase.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed and high insulation voltage is required. The MFP-4 package suits space-constrained PCB layouts. Ensure the application voltage does not exceed the 80 V collector-emitter limit and that the required current transfer ratio falls within the specified 50% to 250% range for reliable switching performance.

Part Context

The FODM214A belongs to the FODM214 series of transistor output optocouplers manufactured by onsemi. This family focuses on providing cost-effective isolation for sensing applications. The device utilizes a phototransistor output architecture, distinguishing it from photovoltaic or logic gate output variants within the broader optocoupler market.
