The APTGL325DA120D3G is a single IGBT module utilizing Trench + Field Stop IGBT4 technology, manufactured by Microsemi Corporation. It features a 1200 V collector-emitter voltage rating and a continuous collector current of 420 A. The module provides a maximum power dissipation of 1500 W and is designed for chassis mounting within the D3 package configuration.
This component is officially classified as obsolete and is no longer manufactured by Microsemi Corporation. Procurement must focus on verifying the authenticity of existing stock from authorized distributors or secondary market suppliers. Buyers should confirm the specific manufacturing date code and storage conditions to ensure device integrity before acquisition.
Engineers selecting this part must account for its discontinued status in new designs. The module requires thermal management compatible with its 1500 W dissipation rating and chassis mount interface. Designers should evaluate alternative components from the same manufacturer family that offer updated availability while maintaining similar electrical specifications and packaging constraints.
The APTGL325DA120D3G belongs to the Microsemi APTGL series of high-voltage IGBT modules. This series utilizes advanced trench gate technology to optimize switching performance and conduction losses. The module integrates an IGBT chip with a parallel fast recovery diode, providing a complete switching solution for high-power electronic applications requiring robust voltage handling capabilities.
No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, engineers must perform manual cross-referencing with current product lines to identify electrically equivalent alternatives.
