APTGF25X120T3G

Overview

The APTGF25X120T3G is a non-punch-through (NPT) fast IGBT power module with an integrated anti-parallel diode, rated for 1200V collector-emitter breakdown voltage and 25A continuous collector current at 80°C case temperature. It features a SP3 isolated package with direct heatsink mounting capability and low junction-to-case thermal resistance of 0.6°C/W for the IGBT and 1.2°C/W for the diode. The device supports switching frequencies up to 50 kHz, includes a Kelvin emitter for simplified drive circuitry, and incorporates an internal NTC thermistor for temperature monitoring. Total gate charge is typically 160 nC at 600V bus voltage.

Procurement Notes

Verify component authenticity by cross-referencing the part number against official Microsemi documentation. Ensure handling procedures account for electrostatic discharge sensitivity as specified in application note APT0502. Confirm that the SP3 package mounting torque remains within the 2 to 3 N.m range for M4 screws to maintain proper thermal interface integrity.

Selection Notes

Select this module when applications require high-frequency switching capabilities up to 50 kHz combined with robust reverse bias safe operating area ratings. The integrated thermistor simplifies thermal management strategies compared to modules requiring external sensing. Ensure gate drive voltages remain within the ±20 V limit and consider the 160 nC total gate charge for driver current sizing.
