Solitron Devices Announces 1200V Silicon Carbide Half Bridge Power Module

October 04, 2021 by Hailey Stewart

The SD11900 series maximizes power density while minimizing loop inductance with a pin configuration to allow simple power bussing.

Solitron has developed the SD11900 series, a 1200V, 50A power module platform to maximize the benefits of SiC, with a uniquely robust, simple, and cost-effective module format. The 37mm x 25mm outline is a fraction of the size and weight of standard 62mm modules.

The SD11902/3/4/5 are half bridge configurations with two 1200V 32mΩ SiC MOSFETs.  The SD11902 and SD11904 feature freewheeling 1200V SiC Schottky diodes in parallel with the MOSFETs inside the module. Two pinout configurations provide flexible power bussing options. Continuous drain current is specified at 50A.

The SD11900 series is designed for demanding applications such as avionics-based electromechanical actuators and power converters. With operating temperatures of -55°C to 175°C, construction includes copper baseplates and Alumina Nitride insulators ensuring TCE matching and high thermal transfer. Isolated integrated temperature sensing enables high level temperature protection.

Silicon Carbide provides excellent switching performance versus the best-in-class silicon MOSFETs and IGBTs with minimal variation versus temperature. Higher efficiency levels than silicon due to significantly lower energy loss and reverse charge results in more switching power and less energy required in the switch-on and switch-off phase. Combined with high switching frequencies this translates to smaller magnetics significantly reducing system weight and size.

Additions to the series which include enhanced performance, alternative pin outs, and higher levels of integration are targeted for release later this year. 

Samples are available from stock.
