FODM2701AR1V

Overview

The FODM2701AR1V is a single-channel transistor output optocoupler manufactured by onsemi. It features a gallium arsenide infrared LED coupled to a silicon phototransistor, providing electrical isolation with a rated isolation voltage of 3750 Vrms. The device is housed in a compact 4-SMD surface-mount package, designed for efficient space utilization in circuit board layouts. Key electrical characteristics include a collector-emitter saturation voltage of 300mV and a minimum current transfer ratio of 50% at a forward current of 5mA. This component is engineered for reliable signal transmission across isolated barriers.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using an infrared LED and phototransistor configuration.
• Utilizes a compact surface-mount package design suitable for automated assembly and dense PCB layouts.
• Ensures stable signal transmission with defined current transfer ratios and low saturation voltage characteristics.

Applications

• Industrial control systems requiring galvanic isolation
• Communication equipment signal interfacing
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'R1V' against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the latest datasheet revision. Check for obsolescence notices as this part may be discontinued or superseded by newer alternatives in the product line.

Selection Notes

Select this component when a single-channel transistor output optocoupler with 3750 Vrms isolation is required. Ensure the application supports the specified current transfer ratio and saturation voltage limits. Verify that the surface-mount footprint matches the available PCB land pattern. Consider thermal management requirements based on the operating environment and duty cycle.

Part Context

This component belongs to the family of transistor output optoisolators from onsemi. These devices are widely used for isolating low-voltage control circuits from higher-voltage power stages. The FODM2701 series typically offers robust performance in noisy environments, making it suitable for applications where signal integrity and safety isolation are critical.

Replacement Considerations

Official substitutes may include other single-channel transistor output optocouplers with similar isolation ratings and pin configurations. Verify compatibility regarding current transfer ratio, propagation delay, and package dimensions before substitution.
