On On introduces smart power modules based on silicon carbide

Shanghai, China - March 18, 2025 - onsemi (NASDAQ: ON) introduced its first generation SPM 31 Smart Power module (IPM) family based on 1200V silicon carbide (SiC) metal-oxide-semiconductor field-effect transistors (MOSFETs). The EliteSiC SPM 31 IPM offers superior energy efficiency and power density in an ultra-compact package size compared to the use of 7th generation Field Cut-off (FS7) IGBT technology, resulting in a lower overall system cost than other leading solutions on the market. These IPMs improve thermal performance, reduce power consumption, and support fast switching speeds, making them ideal for three-phase variable frequency drive applications such as AI data centers, heat pumps, commercial heating, ventilation and air conditioning (HVAC) systems, servo motors, robotics, variable frequency drives (VFDS), and electronic commutator (EC) fans in industrial pumps and fans.The EliteSiC SPM 31 IPM complements the On IGBT SPM 31 IPM portfolio, which covers low currents from 15A to 35A, offering a wide range of current ratings from 40A to 70A. On Semiconductor currently offers industry-leading, broadly scalable, flexible integrated power module solutions in a compact package.

As electrification and AI applications grow, especially as the construction of more AI data centers increases energy demand, reducing the energy consumption of applications in this area becomes increasingly important. In this transition to a low-carbon world, power semiconductors that can efficiently 
As with many other industrial applications such as pumps, EC fans require higher power density and energy efficiency than existing larger IGBT solutions. By switching to the EliteSiC SPM 31 IPM, customers will benefit from smaller size, higher performance, and a simplified design due to high integration, resulting in shorter development times, lower overall system costs, and reduced greenhouse gas emissions. For example, compared to system solutions using the current IGBT Power Integration Module (PIM), the power loss is 500W at 70% load, while the adoption of the efficient EliteSiC SPM 31 IPM can reduce the annual energy consumption and cost of each EC fan by 52%.

The fully integrated EliteSiC SPM 31 IPM includes a separate upbridge gate driver, low voltage integrated circuit (LVIC), six EliteSiC MOSFETs and a temperature sensor (voltage temperature sensor (VTS) or thermistor). Based on industry-leading M3 SiC technology, the module is optimized for hard switching applications with reduced bare chip size and improved short circuit withstand time (SCWT) using the SPM 31 package for industrial variable frequency motor drives. MOSFET adopts three-phase bridge structure, and the lower bridge arm adopts independent source connection, which fully improves the flexibility of selecting control algorithm.

In addition, the EliteSiC SPM 31 IPM includes the following benefits:

The low-loss, short-circuit resistant M3 EliteSiC MOSFETs protect against catastrophic failures of equipment and components, such as electric shock or fire.
Built-in undervoltage protection (UVP) to prevent equipment damage when the voltage is too low.
As a counterpart of the FS7 IGBT SPM 31, customers can choose different current ratings while using the same PCB board.
UL certified to meet national and international safety standards.
Single-ground power supplies provide improved safety, equipment protection and noise reduction.

Simplify design and reduce customer board size thanks to:
Gate driver control and protection
Built-in Bootstrap diode (BSD) and Bootstrap resistor (BSR)
Provides an internal boost diode for the up-bridge grid boost drive
Integrated temperature sensor (VTS output by LVIC and/or thermistor)

Built-in high speed and high voltage integrated circuit
