APTLGL325A1208G

Overview

The APTLGL325A1208G is a power driver module from Microchip Technology, classified as an Intelligent Power Module (IPM) utilizing IGBT technology. It features a half-bridge configuration housed in a 6-PowerSIP LP8 package with screw mount installation. The device supports a maximum collector-emitter voltage of 1.2 kV and delivers a continuous collector current of 420 A at 25°C. Key electrical parameters include a collector-emitter saturation voltage of 1.85 V and a power dissipation rating of 1.4 kW. It operates within a temperature range of -40°C to +85°C and includes integrated isolation of 2500Vrms.

Feature Summary

• Integrates IGBT half-bridge topology with dedicated power drivers for simplified system design
• Includes an integrated DC/DC converter to provide isolated gate drive supply
• Features high-voltage isolation capability between control and power circuits
• Utilizes silicon-based semiconductor technology for robust thermal performance

Applications

• Uninterruptible Power Supplies (UPS)
• Motor Drive Systems
• Switched-Mode Power Supplies (SMPS)

Procurement Notes

Verify the specific part number suffix against official Microchip documentation to ensure correct configuration, as variations may exist within the product family. Confirm that the LP8 package dimensions and pinout match the target PCB layout requirements. Check for any recent Product Change Notifications regarding assembly sites or material composition updates before finalizing procurement specifications.

Selection Notes

Select this component when a compact, high-current solution is required for applications demanding 1.2 kV blocking voltage and up to 420 A continuous current. The integrated driver and DC/DC converter reduce external component count compared to discrete solutions. Ensure the thermal management design can handle the specified 1.4 kW power dissipation within the operating temperature range of -40°C to +85°C.

Part Context

This module belongs to the APTLGT300 series of intelligent power modules from Microchip Technology. It shares the same LP8 package form factor and general interface characteristics as other variants in the family, such as the APTLGT300A1208G, but differs in specific current ratings and saturation voltage parameters defined by its internal die configuration.

Replacement Considerations

The APTLGT300A1208G is a related variant within the same product family sharing the LP8 package. However, it specifies a different continuous collector current of 440 A and a lower saturation voltage of 1.7 V. Direct substitution requires verification that these electrical differences are acceptable for the specific application circuit.
