NXH40T120L3Q1PG

Overview

The NXH40T120L3Q1PG is a Q1 3-phase T-type neutral-point clamped (TNPC) power module manufactured by onsemi. It integrates three channels, each containing two 1200 V, 40 A IGBTs with inverse diodes and two 650 V, 25 A IGBTs with inverse diodes. The device features press-fit pins for board mounting and includes an integrated NTC thermistor. Maximum ratings include a collector-emitter voltage of 1200 V for the main IGBTs and 650 V for the neutral point devices. Continuous collector current reaches 40 A at TC = 80°C, with a maximum operating junction temperature of 175°C.

Feature Summary

• Three-channel TNPC topology integrating high-voltage and low-voltage switching elements
• Press-fit pin configuration for secure PCB attachment
• Integrated NTC thermistor for thermal monitoring
• RoHS compliant and lead-free construction

Applications

• Solar inverters
• Uninterruptible Power Supplies (UPS)
• Energy storage systems

Procurement Notes

Verify the ordering suffix 'PG' confirms the specific package variant with press-fit pins and lead-free compliance as documented in the official datasheet. Confirm that the assembly site code and test site code match the required manufacturing origin. Ensure the procurement documentation references the correct Case 180AS outline to guarantee mechanical compatibility with the intended heatsink and PCB layout.

Selection Notes

Select this component when a compact 3-phase TNPC solution is required for power levels around 40 A. The press-fit option eliminates soldering requirements but necessitates compatible PCB pad designs. Verify that the system can accommodate the 1200 V rating for the half-bridge legs and the 650 V rating for the neutral-point clamping switches. Ensure the thermal management design supports the specified junction temperature limits under expected load conditions.

Part Context

This part belongs to the NXH40T120L3Q1 series of Q1 3-phase TNPC modules. Variants within the series differ primarily in terminal technology; for example, the NXH40T120L3Q1SG utilizes solder pins instead of press-fit connections. All variants share the same internal circuit topology and electrical characteristics defined in the NXH40T120L3Q1 data sheet.

Replacement Considerations

Direct substitutes within the same family include NXH40T120L3Q1SG (solder pins) and NXH40T120L3Q1PTG (press-fit pins). These parts maintain identical electrical performance but require verification of mechanical interface compatibility with the existing PCB footprint.
