FOD053LR1

Overview

The FOD053LR1 is a high-speed optocoupler from onsemi featuring two channels in an 8-pin SOIC package. It consists of an AlGaAs LED optically coupled to a phototransistor detector, supporting data rates up to 1 Mb/s. Key electrical parameters include a minimum current transfer ratio of 19% and a maximum of 50%. The device offers 2500 Vrms isolation voltage, operates within a temperature range of -40°C to 125°C, and has a typical rise/fall time of 5 ns.

Feature Summary

• Dual-channel configuration for simultaneous signal isolation
• High-speed operation with 5 ns switching times
• Robust electrical isolation between input and output circuits

Applications

• Digital isolators for microcontroller interfaces
