Procurement Notes

Verify the specific revision status and manufacturing origin before procurement. Confirm that the SP3 package dimensions align with the target heatsink interface. Ensure electrostatic discharge handling procedures are strictly followed during installation, as specified in application note APT0502.

Selection Notes

Select this component for applications requiring robust short-circuit withstand capability rated at 300 A for 10 µs. Evaluate thermal management requirements based on the 0.4 °C/W junction-to-case thermal resistance. Verify that the operating frequency remains within the 50 kHz limit defined by the switching energy characteristics.

Part Context

This module belongs to the APTGF series of NPT IGBT power modules. It utilizes the SP3 plastic frame housing, which allows for direct mounting to a heatsink while maintaining electrical isolation. The design emphasizes positive temperature coefficient of VCEsat to support easy paralleling of multiple units.

Replacement Considerations

Direct replacements must match the 1200 V rating, SP3 footprint, and pinout configuration. Verify that alternative components maintain comparable switching speeds and thermal resistance values to ensure system performance consistency without redesigning the cooling infrastructure.

FAQ
