FOD250L

Overview

The FOD250L is a high-speed optocoupler featuring an LED input and a totem-pole output stage. It provides electrical isolation between input and output circuits with a rated isolation voltage of 3750 Vrms. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 10 Mbps. Key electrical characteristics include a propagation delay of typically 60 ns and a pulse width distortion of 10 ns. The component is available in an 8-pin DIP package, suitable for digital signal transmission applications requiring galvanic isolation.

Feature Summary

High-speed digital signal transmission capability
Totem-pole output stage for low impedance drive
Galvanic isolation for noise immunity

Applications

Digital communication interfaces
Isolated data acquisition systems
Industrial control networks

Procurement Notes

Verify the specific suffix 'L' indicates the lead-free RoHS-compliant variant when ordering. Confirm the package type matches the required footprint for PCB integration. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the datasheet revision date to confirm current specifications. Validate that the isolation voltage rating meets system safety requirements.

Selection Notes

Select this component when high-speed digital isolation is required over standard logic isolators. Consider the propagation delay and pulse width distortion metrics for timing-critical applications. Evaluate the power consumption relative to system thermal constraints. Compare against alternative optocouplers if higher isolation voltage or different output configurations are needed.

Part Context

This part belongs to onsemi's family of high-speed optocouplers designed for robust digital isolation. It complements other devices in the series offering varying speed and isolation ratings. The technology leverages advanced LED and photodetector integration to achieve reliable performance in noisy environments.
