APT40GP90J

Overview

The APT40GP90J is a single IGBT module from Microchip Technology's POWER MOS 7 series, utilizing PT technology. It features a 900 V collector-emitter breakdown voltage and a maximum continuous collector current of 68 A at 25°C. The device has a maximum power dissipation of 284 W and operates within a junction temperature range of -55°C to 150°C. Key electrical parameters include a saturated collector-emitter voltage of 3.2 V (max) and an input capacitance of 3.3 nF at 25 V. It is housed in an ISOTOP-4 package (SOT-227-4 miniBLOC) with base mounting.

Feature Summary

• ISOTOP® packaging provides high thermal conductivity and reliable electrical isolation for base plate mounting.
• POWER MOS 7™ technology integrates gate drive protection features to enhance system robustness.
• PT (Punch-Through) design ensures stable switching characteristics and controlled tail current.

Applications

• High-frequency motor drives
• Switched-mode power supplies
• Induction heating systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and thermal interface specifications. Ensure that the procurement documentation explicitly references the ISOTOP-4 package variant to avoid confusion with other SOT-227 configurations. Cross-reference the RoHS compliance status with current regulatory requirements for the target market.

Selection Notes

Select this component when a single-switch configuration with 900 V blocking capability is required. The 68 A current rating suits applications demanding moderate power handling in compact footprints. Consider the 3.2 V saturation voltage for efficiency calculations in low-voltage drop scenarios. Verify that the thermal management solution can handle the 284 W dissipation limit under worst-case operating conditions.

Part Context

This part belongs to the APT40GP90 family, which includes variants like APT40GP90B2DQ2G. These devices are designed for hard-switching applications requiring fast recovery and low conduction losses. The ISOTOP package distinguishes it from through-hole TO-247 counterparts by offering superior heat transfer to a printed circuit board or heatsink via the base terminal.

Replacement Considerations

Direct substitutes may include other 900 V single IGBT modules in ISOTOP-4 packages from Microchip or compatible manufacturers. Verify that replacement parts match the 68 A current rating and 284 W power dissipation limits. Check for identical pin assignments and thermal resistance values to ensure mechanical and electrical interchangeability without redesigning the PCB layout.
