FOD073L

Overview

The FOD073L is a high-speed optocoupler featuring an AlGaAs LED optically coupled to a high-gain split Darlington photodetector. It offers low input current of 0.5 mA and a maximum current transfer ratio of 7000% at 500 µA. The device supports operating temperatures from -40°C to +85°C with a power dissipation of 100 mW and output current capability of 60 mA. Typical switching times are 5 µs for turn-on and 25 µs for turn-off. It is designed for LVTTL/LVCMOS compatibility.

Feature Summary

Integrates an AlGaAs LED with a high-gain split Darlington photodetector for enhanced signal isolation.
Features integrated emitter-base resistors to provide superior thermal stability.
Combines ultra-low input current with high current transfer ratio for efficient interface capabilities.

Applications

Interface with MOS logic families
Interface with CMOS logic families
Interface with LSTTL logic families
EIA RS-232C communication interfaces

Procurement Notes

Verify the specific ordering suffix against the official onsemi datasheet to ensure correct packaging and temperature grade specifications. Confirm RoHS compliance status and material composition declarations via the manufacturer's sustainability documentation before finalizing procurement orders.

Selection Notes

Select this component when low drive current is required for interfacing with sensitive logic outputs. The high current transfer ratio allows for robust signal transmission despite minimal input power. Ensure the application environment remains within the specified -40°C to +85°C operational range for reliable performance.

Part Context

This device belongs to onsemi’s portfolio of high-speed optocouplers. It utilizes advanced AlGaAs LED technology paired with specialized photodetectors to achieve fast switching speeds while maintaining electrical isolation standards suitable for digital communication and control circuits.

Replacement Considerations

Consult the official onsemi replacement guide for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' devices without verifying pinout, electrical parameters, and isolation voltage ratings.
