2DIB1401FXUMA1

Overview

The Infineon Technologies 2DIB1401FXUMA1 is a general-purpose digital isolator utilizing capacitive coupling technology. It features two independent channels with unidirectional signal transmission, providing galvanic isolation between circuits. The device supports data rates up to 40 Mbps and offers a minimum common-mode transient immunity of 100 kV/µs. It operates within a supply voltage range of 2.7 V to 6.5 V and functions across an extended temperature range from -40°C to 150°C. The component is housed in an 8-SOIC package with a 3.90 mm width.

Feature Summary

• Provides galvanic isolation between separate electrical circuits using capacitive coupling technology.
• Supports high-speed data transmission with a maximum rate of 40 Mbps for reliable communication.
• Ensures signal integrity in noisy environments through high common-mode transient immunity.

Applications

• Industrial automation systems requiring robust signal isolation
• UART and CAN bus interface isolation
• General-purpose digital isolation in electronic circuits

Procurement Notes

Verify the specific suffix 'XUMA1' to confirm tape-and-reel packaging configuration. Confirm that the part number corresponds to the functional variant intended for your design, as suffixes may indicate packaging or specific binning differences without altering core electrical characteristics. Ensure compatibility with existing PCB footprints and thermal management requirements during integration.

Selection Notes

Select this component when bidirectional isolation is not required, as it supports only unidirectional channels. It is suitable for applications needing moderate data rates up to 40 Mbps rather than ultra-high-speed interfaces. Consider the 8-SOIC package constraints and verify that the 3000 Vrms isolation rating meets the safety standards of the target application environment.

Part Context

This component belongs to the ISOFACE™ dual-channel digital isolator family designed for industrial automation solutions. It serves as a general-purpose isolation device, distinct from specialized gate drivers or power semiconductors offered by the manufacturer. The product line focuses on providing reliable signal transfer across isolated boundaries in demanding electronic environments.

Replacement Considerations

The 2DIB1400FXUMA1 is documented as a parameter-equivalent alternative. Verify pinout compatibility and specific electrical tolerances before substitution, as manufacturing revisions may exist between these closely related part numbers.
