Apex Microtechnology has introduced the MSA303, a new addition to its Integrated Power Module lineup. This module uses Silicon Carbide (SiC) MOSFET technology to deliver higher efficiency compared to similar products. It features three independent half-bridges, each capable of handling up to 40 A of continuous current. Designed on a thermally conductive yet electrically isolated substrate, the MSA303 offers flexible integration and simplifies heat management.
“This device 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.”
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.
MSA303: 600 V, 40 A Silicon Carbide 3-Phase Integrated Power Module
Applications: Motor Drive/Control, Variable Frequency Drives, DC/AC Converters, Power Inverters, and Test Equipment
The MSA303 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.
The MSA303 is currently in volume production with sample units available for qualified applications.
