Bare Die SiC from ROHM Chosen by Apex Microtechnology for Newest Line of Power Modules, Saving Space and Increasing Performance

PublishTime： 2023-03-22 Article Source：ROHM News

ROHM has announced that precision power analog company, Apex Microtechnology, is adopting ROHM’s SiC MOSFETs and SiC Schottky Barrier Diode (SBD) for a new line of power modules. This product family currently includes the three-phase SA310 module, ideal for driving high-voltage BLDC motors, as well as two half-bridge devices, SA110 and SA111, ideal for a wide range of high-voltage applications.

ROHM’s 1,200V S4101 SiC MOSFETs and 650V S6203 SiC SBD are supplied in bare die form, enabling Apex to save space and increase the performance and reliability of its modules. In addition to the SiC devices, Apex’s new line of power modules uses ROHM’s tightly-matched BM60212FV-C gate drivers in Bare Die format, contributing to the high-efficiency operation of high-voltage motors and power supplies.

By using these parts in bare die form, Apex has been able to increase the levels of integration offered by these power modules. According to a study commissioned by the company, such modules are usually 67% smaller than discrete solutions developed by customers. Apex is often able to include not only MOSFETs, gate drivers, and SBDs but also bootstrap supply and bypass capacitors with compact surface mount form factors.

Apex Microtechnology’s portfolio of high power, high precision analog, and mix-signal solutions are used in some of the world’s most demanding applications. Our devices power systems ranging from medical equipment in a surgical suite, to flight instrumentation, to satellites in orbit. With this in mind, Apex designs its products to meet or exceed the most stringent standards throughout the industry, and as such, we seek to partner with suppliers to share our high standards of quality and care. In this respect, ROHM has shined as a supplier of SiC components for Apex. Not only has the service and support we have received from ROHM been excellent, but they have been able to stably supply us throughout the semiconductor shortages, allowing us to continue production and on-time deliveries to our customers. As Apex continues to develop innovative analog and mix-signal solutions in order to solve the industry’s complex challenges, we look forward to additional collaboration with ROHM.

We are excited to help Apex Microtechnology, a part of the Electronics Technologies Group of HEICO Corporation. They design precision power analog monolithic, hybrid, and open-frame components for a wide range of industrial, test, measurement, and other applications. ROHM is the leading company in SiC power semiconductors and has achieved a significant technological lead in this field along with the provision of power solutions combined with gate driver ICs. Together with Apex Microtechnology, we want to further improve the efficiency of high-power applications by fully exploiting the potential of ROHM's strengths in power and analog technologies.
