Overview
The Infineon Technologies 2DIB0400FXUMA1 is a general-purpose digital isolator featuring two independent channels with capacitive coupling technology. It provides a basic isolation voltage of 3000Vrms and supports data rates up to 40Mbps. The device operates within a supply voltage range of 2.7V to 6.5V and offers a common-mode transient immunity of 100kV/µs. Packaged in an 8-SOIC surface-mount format, it functions across an extended temperature range from -40°C to 150°C.
Feature Summary
- Provides galvanic isolation between input and output sides using capacitive coupling technology for signal transmission.
- Features high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
- Supports bidirectional or unidirectional data flow with independent channel configuration options.
Applications
- Switched-mode power supplies (SMPS) requiring isolated feedback control
- Industrial automation systems with noise-sensitive communication interfaces
- Inverter gate drive circuits needing reliable signal isolation
Procurement Notes
Verify the specific suffix FXUMA1 to confirm tape-and-reel packaging and RoHS compliance status. Confirm component availability as lifecycle status may vary by region. Ensure design-in compatibility with existing PCB footprints and voltage levels before finalizing procurement orders.
Selection Notes
Select this component when dual-channel isolation is required within a compact SOIC package. Consider the 40Mbps data rate limit for high-speed applications. Evaluate the 3000Vrms isolation rating against system safety standards. Verify that the operating temperature range meets environmental requirements.
Part Context
This part belongs to the ISOFACE family of dual-channel digital isolators from Infineon Technologies. These devices are designed to replace traditional transformer or optical couplers in modern industrial and automotive applications, offering higher reliability and smaller form factors.
Replacement Considerations
Check for parameter-equivalent alternatives such as the 2DIB0410FXUMA1 if the original part is discontinued. Verify pinout compatibility and electrical specifications before substituting components in existing designs.
