2DIB1411FXUMA1

Overview

The 2DIB1411FXUMA1 is a general-purpose digital isolator from Infineon Technologies, featuring two independent channels with unidirectional signal transmission. It provides a high isolation voltage of 3000Vrms and supports data rates up to 40Mbps. The device exhibits a common-mode transient immunity (CMTI) of at least 100kV/µs, ensuring reliable operation in noisy environments. Electrical specifications 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 is housed in an 8-SOIC package.

Feature Summary

• Provides robust galvanic isolation between input and output sides using capacitive coupling technology.
• Ensures signal integrity in high-noise industrial applications through high common-mode transient immunity.
• Supports bidirectional logic level translation within the specified supply voltage range.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Power electronics control circuits for motor drives and inverters
• Medical equipment needing safe patient isolation barriers

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as this part may be discontinued. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering. Validate that the specific suffix matches the required packaging format for your assembly line.

Selection Notes

Select this component when dual-channel isolation with moderate speed is required. Compare against alternatives like the 2DIB1400FXUMA1 if pinout compatibility is critical. Consider the 2DIB1410FXUMA1 if different pin configurations are acceptable. Evaluate thermal performance and PCB layout constraints associated with the SOIC-8 package for optimal heat dissipation.

Part Context

This device belongs to the ISOFACE family of dual-channel digital isolators designed for industrial automation solutions. It utilizes capacitive coupling technology to transmit signals across the isolation barrier without magnetic components. The series offers various pinout options to accommodate different design requirements while maintaining consistent electrical performance characteristics.

Replacement Considerations

The 2DIB1400FXUMA1 is listed as a parameter-equivalent substitute. Verify pinout compatibility and functional equivalence before substitution. Check datasheet revisions for any changes in mechanical dimensions or electrical parameters that might affect existing designs.
