# Apex Releases New 3-Phase Silicon Carbide Integrated Power Module
Published by [Apex Microtechnology](https://blog.apexanalog.com/author/apex-microtechnology) on Mar 18, 2026 8:55:16 PM
MSA303 delivers compact, high-efficiency motor drive performance with fully integrated gate drive and protection.
Product Overview
Apex Microtechnology announced the release of the [MSA303](https://www.apexanalog.com/products/msa303.html), the latest member of our family of Integrated Power Modules. This device utilizes Silicon Carbide MOSFET technology to improve efficiency over other devices in its class. Three fully independent half-bridges provide 40 A of continuous current.
By integrating three half-bridges, gate drive circuitry, and protection features into a single module, the MSA303 supports system designs where size, weight, and power (SWaP) are critical. Its compact architecture enables high-power delivery within a small footprint, helping engineers optimize space in demanding application environments.
[MSA303 Key Features](https://www.apexanalog.com/products/msa303.html)
[](https://www.apexanalog.com/products/msa303.html)
- Three fully independent half-bridges
- Integrated gate driver
- High output current - 40A
- High voltage supply - 600V
- Compact design - 30.5mm x 41.9mm body size
[**REQUEST A SAMPLE**](https://apexanalog.com/sales/sample_request.html)
The MSA303 is built on a thermally conductive, but electrically isolated substrate to provide versatility and ease in heatsinking. Protection features include under-voltage lockout (UVLO) and Active Miller clamping to improve reliability. Silicon Carbide Schottky Barrier free-wheeling diodes are included in parallel with the body diode of each MOSFET, eliminating the need for external output protection diodes.
The integrated gate drivers provide isolation between the inputs and high-voltage outputs, and by integrating the gate drive with the output MOSFETs, parasitics that impact switching behavior are kept at a minimum. This improves switching characteristics while reducing potential oscillations.
Pushing Boundaries
“The MSA303 represents a significant step forward in power density for high-voltage motor drive applications,” said *Jens Eltze, Director of Business Development at Apex Microtechnology.* “By combining Silicon Carbide MOSFETs, integrated gate drive, and comprehensive protection features into a single module, we enable engineers to reduce design risk, improve efficiency, and accelerate time to market. This product reflects our continued commitment to delivering high-performance power analog solutions for demanding applications.”
