APT75GT120JU3

Overview

The APT75GT120JU3 is a single IGBT module manufactured by Microchip Technology under the ISOTOP trademark. It utilizes silicon technology and features a SOT-227-4 package designed for screw mount installation. The device supports a maximum collector-emitter voltage of 1.2 kV and delivers a continuous collector current of 100 A at 25°C. Key electrical parameters include a collector-emitter saturation voltage of 1.7 V, a gate-emitter leakage current of 500 nA, and a maximum power dissipation of 416 W. The component operates within a temperature range from -55°C to +150°C with a maximum gate-emitter voltage of 20 V.

Feature Summary

• ISOTOP insulated base design provides high thermal conductivity and electrical isolation.

Applications

• Industrial motor drives
• Uninterruptible power supplies (UPS)
• High-frequency welding inverters

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm pinout compatibility and thermal interface specifications. Ensure that the procurement channel sources genuine components bearing the correct manufacturer markings. Cross-reference the datasheet revision date to validate parameter accuracy before integration into production designs.

Selection Notes

Select this component when a single-switch configuration with high voltage blocking capability is required. The SOT-227-4 package offers a balance between current handling capacity and mounting simplicity for medium-power applications. Evaluate thermal management requirements based on the 416 W power dissipation rating and the specified operating temperature limits.

Part Context

This module belongs to the APT series of discrete IGBT modules produced by Microchip Technology. It is part of the ISOTOP family, which integrates the semiconductor chip with an insulated metal substrate. This architecture distinguishes it from standard bare-chip modules by simplifying heatsinking and improving reliability in demanding industrial environments.

Replacement Considerations

Direct replacements must match the 1.2 kV voltage rating, 100 A current capacity, and SOT-227-4 footprint. Verify that alternative single IGBT modules maintain compatible saturation voltage and switching characteristics to ensure circuit performance parity without redesigning the thermal or drive infrastructure.
