951206 - 1200V 100A Replacement IGBT Power Module

High-Performance Power Switching Component

The IGBT 1200V 100A is a critical power semiconductor device designed for the rigorous demands of industrial inverter welding machines. As an Insulated-Gate Bipolar Transistor (IGBT), this module combines the high-efficiency switching capabilities of a MOSFET with the high-voltage and high-current handling of a bipolar transistor. It is engineered to operate at a breakdown voltage of 1200V, providing a substantial safety margin for 400V-600V internal DC bus architectures commonly found in three-phase welding power sources.

With a continuous collector current rating of 100A, this component is capable of managing significant power throughput required for heavy-duty welding processes such as MIG, TIG, and Stick welding. The module features low saturation voltage characteristics, which minimizes conduction losses and heat generation during operation. This efficiency is paramount in maintaining the overall duty cycle and reliability of the welding equipment. The device is housed in a robust package designed for optimal thermal transfer to the machine's heatsink, ensuring stability even under high-load conditions.

This replacement part is essential for maintenance, repair, and operations (MRO) professionals servicing ESAB and similar industrial inverter equipment. Failure of an IGBT often results in a complete loss of output or machine shutdown. Replacing a faulty module with this high-specification component ensures the equipment returns to its original factory performance levels, adhering to strict electrical safety and operational standards.
