1ED3143MC12HXUMA1

Overview

The Infineon Technologies 1ED3143MC12HXUMA1 is a single-channel isolated gate driver from the EiceDRIVER X3 family, utilizing coreless transformer technology for signal transmission. It features a PG-LDSO-8 surface-mount package and supports an output supply voltage range of 12.35 V to 32 V. The device delivers peak output currents of 6 A (low) and 6.5 A (high). Key electrical parameters include a maximum propagation delay of 50 ns, rise and fall times of 20 ns, and a minimum common-mode transient immunity of 300 kV/µs. It operates within a temperature range of -40°C to +125°C and provides 3000 Vrms isolation.

Feature Summary

• Coreless transformer technology enables high-speed data transmission across the isolation barrier with excellent noise immunity.
• Integrated active shutdown and short-circuit clamp functions protect connected power switches during fault conditions.
• Independent output undervoltage lockout (UVLO) allows flexible configuration relative to GND2 or adjustable thresholds.

Applications

• Electric vehicle charging systems
• Solar inverters and energy storage systems
• High-voltage DC-DC converters and AC drives

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and tape/reel specifications. Confirm that the required isolation voltage ratings meet specific safety standards such as UL 1577 or IEC 60747-17 for your application. Check moisture sensitivity levels and recommended reflow soldering profiles prior to assembly.

Selection Notes

Select this component when high common-mode transient immunity and fast switching speeds are required for silicon carbide or silicon MOSFETs. The PG-LDSO-8 package offers a compact footprint suitable for dense PCB layouts. Ensure the input logic voltage aligns with the 3 V to 6.5 V operating range for compatibility with standard microcontrollers.

Part Context

This device belongs to the EiceDRIVER X3 Compact IC series, designed specifically for driving IGBTs and SiC MOSFETs in demanding industrial environments. The family emphasizes reliability through robust isolation barriers and integrated protection features, supporting applications requiring high efficiency and rapid dynamic response.

Replacement Considerations

The 1ED3143MC12H is the base part number without the specific manufacturing tape-and-reel suffix. Verify pinout compatibility before substituting with other X3 family members like the 1ED3141MC12HXUMA1, noting differences in output current capabilities.
