VS-GB400TH120N

Overview

The VS-GB400TH120N is a high-power Insulated Gate Bipolar Transistor (IGBT) module manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the INT-A-PAK package and features a half-bridge configuration with trench IGBT technology. The device supports a maximum collector-emitter voltage of 1200 V and delivers a continuous collector current of 400 A at 25 °C. Key electrical parameters include a saturation voltage of 1.9 V, a power dissipation rating of 2.3 kW, and a maximum operating junction temperature of +175 °C. The module employs screw mount installation for secure integration into industrial power systems.

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer confirmation. Request official datasheets and RoHS compliance documentation prior to procurement. Confirm that the specific ordering suffix matches the required technical specifications, as variations may exist within the product family. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package degradation before assembly.

Selection Notes

Evaluate the thermal resistance characteristics against the intended heatsink design to ensure adequate cooling for the 2.3 kW dissipation rating. Verify that the drive circuitry can accommodate the gate charge requirements for reliable switching at the target frequency. Assess the short-circuit withstand capability relative to the protection logic speed in the application. Confirm that the 1200 V blocking voltage provides sufficient margin for transient voltage spikes in the DC link.

Part Context

This component belongs to the VS-GB series of high-power IGBT modules from Vishay. The series is engineered for demanding power conversion applications requiring high current density and rugged operation. The VS-GB400TH120N represents a specific current rating variant within this lineup, distinguished by its 400 A capacity and 1200 V voltage class, utilizing the standardized INT-A-PAK form factor common to the family.

Replacement Considerations

Cross-reference pinouts and thermal pad dimensions with alternative manufacturers such as Infineon or Mitsubishi. Verify that substitute modules offer equivalent or superior short-circuit ratings and gate threshold voltages to maintain system stability without redesigning the driver stage.
