2DIB0411FXUMA1

Overview

The Infineon Technologies 2DIB0411FXUMA1 is a general-purpose digital isolator featuring two channels with a unidirectional input configuration of 2/0. It utilizes capacitive coupling technology to provide electrical isolation rated at 3000Vrms. The device supports data rates up to 40Mbps and offers a common-mode transient immunity (CMTI) of 100kV/µs. Key timing parameters include a maximum propagation delay of 33ns for both low-to-high and high-to-low transitions, with a typical rise and fall time of 4ns. It operates on a supply voltage range of 2.7V to 6.5V and functions within an industrial temperature range of -40°C to 150°C. The component is housed in an 8-SOIC package.

Feature Summary

• Provides robust galvanic isolation between circuit sections using capacitive coupling technology.
• Features dual-channel architecture with unidirectional signal transmission capability.
• Ensures signal integrity in noisy environments through high common-mode transient immunity.
• Supports high-speed digital communication with data rates up to 40Mbps.

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Power electronics control circuits needing feedback isolation
• General-purpose digital signal transmission across isolation barriers

Procurement Notes

Verify the specific suffix FXUMA1 to confirm tape-and-reel packaging and RoHS compliance status. Confirm that the 2/0 channel configuration matches the design requirements, as other variants may offer bidirectional or different channel counts. Check current lifecycle status, as availability may vary compared to newer generation replacements. Ensure the 8-SOIC footprint aligns with the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel, unidirectional isolator is required for cost-sensitive applications. The 3000Vrms isolation rating suits most low-voltage industrial standards. Consider the 40Mbps speed limit against higher-speed alternatives if data throughput exceeds this threshold. The wide operating temperature range makes it suitable for harsh industrial environments without additional thermal management.

Part Context

This part belongs to the ISOFACE™ family of dual-channel digital isolators from Infineon Technologies. These devices are designed for industrial automation solutions, offering a compact alternative to traditional magnetic isolators. The 2DIB series focuses on providing reliable signal isolation with low power consumption and small form factors, integrating seamlessly into modern electronic designs.

Replacement Considerations

The 2DIB1400FXUMA1 is listed as a parameter-equivalent replacement, though it is obsolete. Newer equivalents such as the 2DIB1410FXUMA1 and 2DIB1411FXUMA1 are available. Verify pin compatibility and electrical specifications when substituting these parts to ensure seamless integration into existing designs.
