Silicon carbide module maximises benefits of SiC

The CAB425M12XM3 is the newest addition to Wolfspeed’s XM3 power module platform, developed to maximise the benefits of SiC, while keeping the module and system design robust, simple and cost effective.

With half the weight and volume of a standard 62 mm module, the XM3 power module maximizes power density while minimising loop inductance and enabling simple power bussing.

The XM3’s SiC-optimised packaging enables 175°C continuous junction operation, with a high-reliability silicon nitride (Si3N4) power substrate to ensure mechanical robustness under extreme conditions.

The CAB425M12XM3 targets applications with maximum current requirements at high switching frequencies, focused on power density, including vehicle fast chargers, uninterruptable power supplies, motor and traction drives, and smart-grid or grid-tied distributed generation.

Key features of the CAB425M12XM3 include a module size of 80 mm x 53 mm x 19 mm, a blocking voltage of 1200V and current rating at 425A.

It comes in a half bridge configuration and XMX3 package.

Maximum junction temperature is 175 °C

An associated inverter reference design, the CRD250DA12E-XM3, is also available.
