FODM2705

Overview

The FODM2705 is a single-channel transistor output optocoupler featuring two inverse-parallel gallium arsenide infrared emitting diodes for AC input operation. It provides 3750 Vrms isolation voltage and supports a maximum collector-emitter voltage of 40 V with a peak collector current of 80 mA. The device exhibits a typical rise time of 3 µs and a minimum current transfer ratio of 50%. Designed for surface mount installation in a 4-pin Mini-Flat package, it operates within a temperature range of -40°C to 110°C.

Feature Summary

Dual inverse-parallel infrared diodes enable direct AC input signal coupling without external rectification.
High insulation capability ensures safe electrical isolation between input and output circuits.
Compact surface-mount packaging facilitates automated assembly and space-constrained designs.

Applications

AC mains detection and monitoring circuits
Solid-state relay driver interfaces
Industrial control system isolation

Procurement Notes

Verify the specific ordering suffix (e.g., R2) against the manufacturer's official datasheet to confirm tape-and-reel packaging quantities and lead times. Ensure compliance with RoHS directives and safety certifications such as UL and VDE before finalizing procurement orders.

Selection Notes

Select this component when AC input sensing is required without additional rectifier components. The 40 V collector-emitter rating suits low-voltage switching applications. Verify that the 3 µs switching speed meets the timing requirements of the target circuit design.

Part Context

This device belongs to the FODM series of onsemi phototransistor output optocouplers. It utilizes a full-pitch Mini-Flat package designed for standard surface-mount technology processes. The series emphasizes high isolation reliability for industrial and commercial power management applications.
