Overview
The Infineon Technologies 4DIR0401HAXUMA1 is a four-channel digital isolator from the ISOFACE family, designed for high-voltage automotive applications. It features magnetic coupling technology with a data rate of 40 Mbps and a propagation delay of 33 ns. The device offers reinforced isolation voltage of 5700 Vrms and a common-mode transient immunity of 100 kV/µs. Operating within a temperature range of -40°C to +125°C, it is housed in a PG-DSO-Wide-16 package and holds AEC-Q100 qualification.
Feature Summary
- Provides robust reinforced isolation suitable for demanding high-voltage environments
- Utilizes magnetic coupling technology for reliable signal transmission
- Delivers high-speed data transfer capabilities for rapid system operations
Applications
- High-voltage automotive systems requiring galvanic isolation
- Automotive electronic control units (ECUs)
- Industrial automation interfaces
Procurement Notes
Verify component authenticity through official Infineon channels or authorized distributors. Confirm AEC-Q100 qualification status and RoHS compliance against current datasheets. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly. Validate package integrity upon receipt to prevent handling damage.
Selection Notes
Select this component when four isolated channels are required for automotive-grade reliability. Consider its 5700 Vrms isolation rating for high-potential separation needs. Evaluate the 40 Mbps data rate against system timing constraints. Ensure compatibility with the PG-DSO-Wide-16 footprint during PCB layout design.
Part Context
Part of the ISOFACE 4DIRx4xxHA family, the 4DIR0401HAXUMA1 specializes in bidirectional or unidirectional isolation depending on variant configuration. It serves as a critical interface between low-voltage logic and high-voltage power stages in modern vehicle architectures.
Replacement Considerations
Consult official Infineon documentation for qualified substitutes. Verify pinout compatibility and electrical parameter equivalence before substitution.
