FOD053L

Overview

The FOD053L is a dual-channel high-speed optocoupler manufactured by onsemi. It integrates an AlGaAs infrared LED with two phototransistor outputs in an 8-pin SOIC package. The device supports data rates up to 1 Mb/s and provides 2500 Vrms isolation voltage. Key electrical parameters include a typical current transfer ratio of 15% at 16 mA forward current, a maximum collector current of 8 mA, and a power dissipation of 100 mW. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Dual-channel configuration for simultaneous signal isolation
• High-speed data transmission capability
• Robust electrical insulation between input and output circuits

Applications

• Logic gate interface applications requiring isolation
• Data communication systems
• Industrial control systems

Procurement Notes

Verify the specific suffix (e.g., L) against the datasheet to confirm pinout and packaging details. Confirm RoHS compliance status as indicated in official documentation. Ensure the selected variant matches the required channel count and isolation voltage for the target design.

Selection Notes

Select this component when dual-channel isolation is required within a compact surface-mount footprint. Consider the 1 Mb/s speed limit and 2500 Vrms isolation rating against system requirements. Evaluate the phototransistor output characteristics for compatibility with downstream logic levels.

Part Context

This part belongs to the FOD050 series of high-speed optocouplers. The series typically includes single-channel variants like the FOD050L and dual-channel versions like the FOD053L. These devices are designed for applications needing fast data transfer with galvanic isolation.

Replacement Considerations

Check for direct substitutes such as the FOD050L if only one channel is needed. Verify pin-to-pin compatibility with other dual-channel SOIC-8 optocouplers from different manufacturers before substitution.
