Procurement Notes

Verify the specific ordering suffix when purchasing. The suffix 'T' indicates the inclusion of pre-applied phase change thermal interface material, whereas the absence of this suffix denotes the module without it. Confirm UL STD 1557 compliance requirements for your system design. Ensure gate driver compatibility with the specified operating voltages before integration.

Selection Notes

Select this module for high-voltage applications requiring robust 2300 V blocking capability. Evaluate the thermal management strategy based on the 0.145 °C/W junction-to-heatsink resistance. Consider the 150 A continuous current limit relative to your heatsink temperature. Verify that the press-fit mounting method aligns with your mechanical constraints and torque specifications.
