4DIR1400HXUMA1

Overview

The Infineon Technologies 4DIR1400HXUMA1 is a four-channel SPI digital isolator utilizing magnetic coupling technology. It provides a high isolation voltage of 5700 Vrms and supports data rates up to 40 Mbps with a common-mode transient immunity of 100 kV/µs. The device operates within a supply voltage range of 2.7 V to 6.5 V and features propagation delays of 26 ns maximum. Designed for surface mount applications, it is housed in a 16-SOIC package (0.295 inch width) and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides robust electrical isolation via magnetic coupling technology for signal integrity
• Supports bidirectional data transmission across four independent channels
• Ensures precise timing performance with low power consumption characteristics

Applications

• Switching mode power supplies (SMPS)
• Telecommunications equipment
• Electric vehicle (EV) systems

Procurement Notes

Verify component status as the manufacturer indicates this part is obsolete and scheduled for discontinuation. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing design constraints before procurement due to potential end-of-life restrictions. Check for valid RoHS compliance documentation and moisture sensitivity level ratings during acquisition.

Selection Notes

Select this component when high channel count and robust isolation are required for SPI interfaces. Consider the specific package dimensions and thermal requirements for the target application. Evaluate the trade-off between the established 40 Mbps speed and the current obsolescence status against available alternative solutions.

Part Context

This device belongs to the ISOFACE family of digital isolators from Infineon Technologies. The series is characterized by precise timing and low power consumption, designed to replace traditional optocouplers in modern electronic designs requiring reliable galvanic isolation.

Replacement Considerations
