HH75N120 IGBT 1200V 75A Power Semiconductor – Heavy-Duty Transistor for Industrial Inverters & Welders

Overview

The HH75N120 is a robust Trench Field Stop IGBT designed for high-voltage, high-current applications where failure is not an option. With a breakdown voltage of 1200V and a continuous current capacity of 75A, this device is built to handle the “dirty” power environments found in heavy machinery and industrial-grade renewable energy setups.

Key Features 

• 1200V Breakdown Voltage: Provides superior headroom for high-voltage systems (e.g., 3-phase AC motor drives).

• High Current Density: 75A capacity ensures the device can handle massive power throughput without excessive thermal stress.

• Trench Field Stop Technology: Offers excellent trade-off between switching losses and conduction losses , increasing your system’s overall efficiency.

• TO-247 Package: Industry-standard footprint for easy heat sink mounting and thermal management.

• High Ruggedness: Designed specifically for the high-frequency switching and harsh electrical noise typical of industrial welding and inverter hardware.

Technical Specifications 

Common Industrial Applications

• 3-Phase Motor Drives: Efficient control for large factory-grade induction motors.

• Industrial Welding Machines: The high 1200V rating makes this a preferred part for arc welding power supplies.

• Solar Inverters: Critical for high-voltage grid-tie inverters.

• Uninterruptible Power Supplies (UPS): Ideal for heavy-duty industrial UPS systems.
