FODM1008R2

Overview

The FODM1008R2 is a single-channel transistor output optocoupler manufactured by onsemi, designed for surface-mount applications in SOP-4 packages. It features an NPN phototransistor output with a maximum collector-emitter voltage of 70 V and a continuous collector current rating of 50 mA. The device provides high isolation capability with an insulation voltage of 5000 Vrms. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.4 V, and a collector-emitter saturation voltage of 300 mV. The current transfer ratio ranges from 130% to 260%, with typical rise and fall times of 5.7 µs and 8.5 µs, respectively. It operates within a temperature range of -40°C to +110°C.

Feature Summary

• Provides galvanic isolation between input and output circuits using optical transmission.
• Features a robust NPN phototransistor output suitable for digital signal switching.
• Supports high-voltage isolation requirements with a 5000 Vrms insulation rating.

Procurement Notes

Verify the specific suffix R2 indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management considerations align with the specified power dissipation limits during operation. Cross-reference datasheet revisions to confirm parameter consistency for long-term production stability.

Selection Notes

Select this component when a single-channel transistor output is required for cost-effective isolation. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the current transfer ratio range against load requirements to ensure reliable switching. Verify package compatibility with existing PCB footprint constraints for SOP-4 mounting.
