ACEPACK DRIVE is a compact power module tailored for hybrid and electric vehicles traction applications, capable to satisfy the growing demand by car makers for ever greater powers and efficiency solutions.

This power module is based on silicon carbide 3rd generation Power MOSFETs, a well-known and recognizes technology developed by ST that guarantees a very low RDS(on), limited switching energies, and outstanding performances in synchronous rectification working mode, maximizing the mileage range of electric vehicles and efficiency as well as enabling the usage of smaller battery pack. Thanks to its characteristics it can be used in any other motor control application that requires high efficiency and high-power capability.

ACEPACK DRIVE was designed as an all-in-one solution with an incredible high power-density able to reduce the time to market. It’s available in different AC bus bar options and with an embedded NTC that makes it very easy to use and implement in your system, moreover the industry-standard footprint reduces the design effort of the driving board. This module, thanks to the sintering process of the die to substrate and the press fit connections, guarantees a high reliable and long-lasting application.
It represents a technology breakthrough for ST, since it’s the first direct liquid cooled solution available in our portfolio, which leads to a remarkable improvement in thermal performance. ACEPACK DRIVE power module belongs to our STPOWER family.


The ACEPACK DRIVE brand is specifically optimized for main traction inverter applications in the automotive field.
