APTGF50SK120TG

Overview

The APTGF50SK120TG is a single NPT IGBT power module manufactured by Microsemi Corporation. It features a collector-emitter breakdown voltage of 1200 V and a continuous collector current rating of 75 A at case temperature. The module supports a maximum power dissipation of 312 W and utilizes the SP4 baseplate mounting package. Designed for high-voltage switching applications, it integrates standard gate drive requirements with robust thermal management capabilities suitable for industrial power conversion systems.

Feature Summary

• NPT (Non-Punch-Through) IGBT technology for improved short-circuit ruggedness
• Single configuration optimized for compact power circuit designs
• SP4 baseplate mounting style for efficient heat transfer to cooling systems

Applications

• Industrial motor drives and variable frequency drives
• DC-DC buck chopper converters
• Uninterruptible power supply (UPS) inverters

Procurement Notes

Verify component authenticity through authorized Microsemi distributors or certified partners. Confirm that the specific part number matches the required electrical specifications for your design. Check for RoHS compliance status and ensure proper handling procedures are followed due to the sensitive nature of semiconductor devices. Validate packaging integrity upon receipt to prevent damage during storage and installation.

Selection Notes

Select this module when a 1200 V blocking capability and 75 A continuous current are required in a single-chip configuration. The SP4 package offers a balance between current capacity and physical footprint for medium-power applications. Ensure the gate drive circuitry aligns with standard IGBT voltage thresholds and consider thermal resistance characteristics for heatsink selection to maintain junction temperatures within safe operating limits.

Part Context

This component belongs to Microsemi's Activator-Power series of discrete semiconductors and modules. The product line focuses on high-voltage silicon solutions for demanding power electronics environments. As a discontinued item at major distributors, it represents legacy hardware often found in existing industrial equipment designs requiring maintenance or replacement.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers must evaluate pin-compatible alternatives from current Microchip Technology portfolios or perform full re-evaluation of thermal and electrical parameters when selecting modern replacements.
