APTDX300A170D16AG

Overview

The APTDX300A170D16AG is a fast diode phase-leg power module manufactured by Microchip Technology. It features a peak repetitive reverse voltage of 1700 V and an RMS isolation voltage of 4000 V. The device supports a DC forward current of 300 A at a case temperature of 50 °C, with a maximum non-repetitive forward surge current of 1500 A. The typical forward voltage is 2.35 V at 300 A and 25 °C. Operating junction temperatures range from -40 °C to 175 °C.

Feature Summary

• Soft-recovery characteristics for low-noise switching
• Aluminum Nitride (AlN) substrate for improved thermal performance
• M6 power connectors for direct mounting to heatsink

Applications

• Uninterruptible Power Supply (UPS)
• Induction heating
• Welding equipment
• High-speed rectifiers

Procurement Notes

Verify the specific datasheet revision DS00005278A against your design requirements. Confirm that the M6 mounting torque specifications align with your mechanical assembly capabilities. Ensure electrostatic discharge handling procedures are strictly followed during installation due to component sensitivity.

Selection Notes

Select this module when high blocking voltage and soft recovery are required for efficient power conversion. The AlN substrate provides lower thermal resistance compared to standard substrates. Verify that the operating case temperature remains within the specified limits to maintain the rated 300 A forward current capability.

Part Context
