GCMX040A120B2B1P

Overview

The GCMX040A120B2B1P is a Silicon Carbide (SiC) MOSFET module manufactured by SemiQ, belonging to the GCMX series. It features an N-Channel configuration with a drain-source breakdown voltage of 1.2 kV and a continuous drain current of 56 A at case temperature. The device exhibits a maximum on-resistance of 52 mOhms at 40 A and 20 V gate drive. Key switching parameters include a typical turn-on delay of 22 ns, turn-off delay of 42 ns, rise time of 8 ns, and fall time of 16 ns. It operates within a junction temperature range of -40°C to +175°C and supports screw mount installation.

Feature Summary

• Utilizes Silicon Carbide technology for high-temperature operation up to 175°C
• Designed as a half-bridge module to reduce component count in power electronics
• Features low switching losses with fast rise and fall times

Applications

• High-power electric vehicle drivetrains
• Industrial motor drives and inverters
• High-frequency power supply designs

Procurement Notes

Verify the specific suffix B1P against official SemiQ documentation to confirm pinout and thermal interface specifications. Ensure compatibility with existing gate driver requirements for the specified threshold voltage. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this module when a robust half-bridge configuration is required for 1200V applications. The 52 mOhm on-resistance offers a balance between conduction loss and cost compared to lower resistance alternatives. Verify that the 56 A current rating meets the peak load requirements of the target circuit design.

Part Context

This component is part of SemiQ's QSiC Gen3 portfolio, which focuses on high-reliability SiC MOSFETs. The GCMX series utilizes ceramic pressure contact via packaging to enhance thermal performance and mechanical stability. This specific model provides a pre-configured half-bridge solution, simplifying layout and reducing parasitic inductance in high-speed switching environments.

Replacement Considerations

Direct replacements must match the 1200V rating, half-bridge topology, and similar Rds(on) characteristics. Verify pin compatibility and thermal pad dimensions before substitution. Consult SemiQ datasheets for alternative GCMX models with adjusted current ratings if higher or lower capacity is needed.
