onsemi CM1248-08DE: Powering the Next Generation of High-Efficiency Systems
The relentless pursuit of greater efficiency, power density, and reliability in power electronics has ushered in the widespread adoption of wide bandgap semiconductors. At the forefront of this revolution is the onsemi CM1248-08DE, a high-performance silicon carbide (SiC) power module engineered to meet the demanding requirements of modern industrial and energy infrastructure.
This module integrates a half-bridge configuration utilizing onsemi's advanced Gen 2 SiC MOSFET technology. These MOSFETs are renowned for their superior switching performance, which is a critical advantage over traditional silicon-based IGBTs. The CM1248-08DE operates at a blocking voltage of 1200 V and features a low continuous drain current rating, making it an ideal solution for applications where fast switching and minimizing losses are paramount.
A key benefit of this SiC power module is its dramatic reduction in switching losses. Silicon Carbide technology enables significantly higher switching frequencies, which allows designers to shrink the size of passive components like inductors and capacitors. This leads to the development of more compact and lighter end-products without compromising on performance or efficiency. Furthermore, the module's low on-resistance (RDS(on)) contributes to lower conduction losses, enhancing overall system efficiency, particularly in high-power applications.
The module is designed for robustness and longevity. It features a low-inductance design that minimizes voltage overshoot during fast switching transients, thereby improving system reliability. The use of sintered die-attach technology enhances the power cycling capability and thermal performance, ensuring stable operation even under strenuous conditions. Its baseplate is electrically isolated, simplifying thermal management and mechanical integration into heatsinks.
Target applications for the onsemi CM1248-08DE are diverse and critical to the energy transition, including:
Solar and renewable energy inverters
Energy storage systems (ESS)
Uninterruptible power supplies (UPS)
Industrial motor drives and EV charging infrastructure
ICGOODFIND: The onsemi CM1248-08DE stands as a testament to the maturity and advantages of SiC technology, offering engineers a robust, high-efficiency building block to create the next generation of power conversion systems that are smaller, cooler, and more efficient than ever before.
