Apex Microtechnology Expands Integrated Power Module Family with New 600 V, 40 A Silicon Carbide 3-Phase Module
TUCSON, Arizona, U.S.A. – March 19, 2026 – Apex Microtechnology today announced the release of the MSA303, the latest member of its family of Silicon Carbide Integrated Power Modules. The module 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. MSA303 is built on a thermally conductive, but electrically isolated substrate to provide the most versatility and ease in heatsinking.
“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 analog power solutions for demanding applications.”
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 considerations. Its compact architecture enables high power delivery within a small footprint, helping engineers optimize space in demanding application environments.
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, improving switching characteristics while reducing potential oscillations.
Applications include, but are not limited to: Motor Drive/Control, Variable Frequency Drives, DC/AC Converters, Power Inverters, and Test Equipment.
