FODM8801CR2V

Overview

The FODM8801CR2V is a single-channel transistor output optocoupler from the OptoHiT series, manufactured by onsemi. It features an NPN phototransistor output with a maximum collector-emitter voltage of 75 V and a peak collector current of 30 mA. The device provides high isolation capability with an insulation voltage of 3750 Vrms. Key electrical parameters include a forward current of 20 mA, a forward voltage of 1.8 V, and a collector-emitter saturation voltage of 400 mV. The current transfer ratio ranges from 200% to 400%. Dynamic performance includes a rise time of 5 µs and a fall time of 5.5 µs. It operates within a temperature range of -40°C to +125°C and is housed in a 4-Mini-Flat surface-mount package.

Feature Summary

• High-temperature stability designed for demanding thermal environments
• Enhanced safety insulation rated at 3750 Vrms for reliable signal isolation
• Fast switching speeds with microsecond-level rise and fall times
• Compact Mini-Flat surface-mount packaging for space-constrained designs

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops and monitoring circuits
• Communication interfaces for noise immunity
• Microcontroller input/output isolation

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm RoHS compliance status and REACH material declarations prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain device reliability during assembly processes.

Selection Notes

Select this model when high-temperature operation and robust isolation are required. The wide current transfer ratio range accommodates various drive conditions. Consider the Mini-Flat footprint for PCB layout constraints. Validate that the 75 V output voltage rating meets the specific circuit load requirements.

Part Context

This component belongs to the FODM8801 family of transistor output optocouplers. Variants such as FODM8801A and FODM8801B offer different current transfer ratio specifications while maintaining similar electrical characteristics and packaging. The CR2V suffix indicates a specific tape and reel packaging configuration suitable for automated surface-mount assembly.

Replacement Considerations

Direct substitutes within the same family include FODM8801C and FODM8801BR2V. Verify that alternative part numbers match the required current transfer ratio and packaging type before implementation.
