APTGF15X120T3G

Overview

The APTGF15X120T3G is a non-punch-through (NPT) fast IGBT power module manufactured by Microsemi. It features a SP3 isolated package with screw mounting and an integrated NTC thermistor for temperature monitoring. Key electrical parameters include a collector-emitter breakdown voltage of 1200 V, a continuous collector current of 15 A at 80°C case temperature, and a maximum gate-emitter voltage of ±20 V. The module exhibits a typical saturation voltage of 3.2 V at 25°C and supports switching frequencies up to 50 kHz. Thermal resistance from junction to case is 0.9 °C/W for the IGBT and 2 °C/W for the diode.

Procurement Notes

Verify component authenticity through authorized Microsemi distributors or official channels. Confirm datasheet revision status prior to integration. Ensure electrostatic discharge handling procedures are strictly followed during assembly. Validate that the specific ordering suffix matches the required package and terminal configuration for the target application design.

Selection Notes

Select this module for applications requiring high-frequency operation up to 50 kHz with moderate current levels. Consider the 1200 V rating for medium-voltage industrial environments. Evaluate the SP3 package dimensions and M4 mounting torque requirements against the mechanical constraints of the heatsink interface. Verify compatibility with the integrated NTC thermistor readout circuitry for accurate thermal protection.
