Infineon 900546 Power Module (Batch G1031) – Dual IGBT Half-Bridge (Used / Tested)

The Infineon 900546 Power Module is a high-reliability semiconductor device engineered for demanding switching applications. Manufactured by Infineon Technologies (formerly Eupec), this module is an OEM (Original Equipment Manufacturer) component, typically custom-built for top-tier automation brands like Rockwell Automation, Siemens, or ABB. The date code G1031 indicates a manufacturing date of 2010 (Week 31), representing a mature and stable production run of this robust silicon technology.

Condition and Verification Process Infineon 900546 Power Module (Batch G1031)

 We prioritize transparency in the industrial surplus market. This item is sold as USED.

• Cosmetic Condition: The unit shows signs of previous installation, including minor scratches on the plastic housing and oxidation on the copper terminals. Traces of thermal compound may remain on the nickel-plated baseplate. These are purely cosmetic and do not compromise the dielectric strength.

• Testing Protocol: Since we do not use a high-voltage dynamic test bench, this module has undergone a strict static verification using a multimeter. We guarantee:

  1. No short circuits between the Collector and Emitter (C-E).

  2. The Gate-Emitter junctions measure high impedance (no leakage).

  3. The internal freewheeling diodes are functional in forward bias.

Technical Specifications (Based on 62mm Standard Architecture)
While the “900546” part number is proprietary, the physical architecture corresponds to the industry-standard 62mm EconoDUAL or FF Series package. Based on the form factor, the estimated specifications are:

• Configuration: Half-Bridge (Dual Switch). Two IGBTs connected in series internally.

• Voltage Class (Vces): 1200V (Standard for this package size in industrial drives).

• Current Rating (Ic): 300A to 400A (Continuous DC Current at Tc=80°C).

• Chip Technology: Likely IGBT3 or IGBT4 TrenchStop™ technology for low switching losses.

• Baseplate: Copper with Nickel plating for superior thermal conductivity.

• Mounting: Standard M6 Screw terminals for power; faston/solder pins for gate control.

Common Applications
This Infineon 900546 Power Module is critical for the maintenance of legacy systems where new parts are obsolete or prohibitively expensive. It is commonly found in:

• AC Motor Drives: Main inverter stage for pumps, fans, and conveyor belts.

• Traction Inverters: Control systems for electric forklifts and heavy mining vehicles.

• Renewable Energy: Solar inverters and wind turbine converters.

• UPS Systems: Large-scale Uninterruptible Power Supplies.

About the Manufacturer
Infineon Technologies AG, a spin-off from Siemens, is a global leader in power semiconductors. Their “Brick” style modules are legendary in the engineering world for their ability to withstand thermal cycling and high surge currents. By choosing an original Infineon OEM part, you ensure electrical compatibility and mechanical robustness that generic knock-offs cannot match.

Frequently Asked Questions (FAQ)

Is the Infineon 900546 Power Module compatible with my broken G0850 unit?
Yes, they are 100% interchangeable. The critical identifier is the Part Number 900546. The codes “G1031” and “G0850” are simply Date Codes (manufacturing dates). This unit (G1031) is actually newer than a G0850 unit.

How should I install this used power module?
Installation requires precision. You must thoroughly clean the heatsink surface and the module’s baseplate. Apply a thin, uniform layer of high-grade thermal grease. Tighten the mounting screws to the torque specified in your equipment’s service manual (usually 3-6 Nm for M6 screws) to prevent cracking the ceramic substrate.

Do you accept returns if it doesn’t work?
The item is sold as “Used/Tested” with a “No DOA” (Dead on Arrival) guarantee based on our static multimeter tests. However, due to the risk of installation errors or external circuit failures (like a bad gate driver board) damaging the module instantly, we cannot offer a long-term warranty once installed.

What does “OEM Part” mean in this context?
OEM means Infineon manufactured this specific module for a third-party company (like Allen-Bradley or Siemens) to put inside their drives. That is why you cannot find a public datasheet for “900546,” but the internal silicon is standard, high-quality Infineon technology.
