What CoolCAD Electronics, LLC does

CoolCAD Electronics, LLC is a Maryland-based, privately held semiconductor design and fabrication company founded in 2008 as a spinoff of the University of Maryland's Electronics Modeling & Mixed Signal Group by UMD ECE Professor Dr. Neil Goldsman and Dr. Akin Akturk. The company specializes in wide bandgap silicon carbide (SiC) devices that operate at temperatures up to 500°C, significantly exceeding the ~200°C ceiling of conventional silicon. Its product portfolio spans SiC power MOSFETs (650V-3300V), SiC Schottky and JBS diodes, high-temperature SiC CMOS integrated circuits, deep-UV avalanche and linear photodiodes, UV focal plane arrays, flame detectors, evaluation boards and reference DC-DC converter designs, supported by the proprietary CoolSPICE circuit and thermal simulation software (built on the open-source ngspice engine).

The company monetizes across four revenue streams: hardware sales of standard SiC components (distributed via Digikey and direct quote), one-time and annual CoolSPICE software licenses (with a free Student/Evaluation tier), micro-fabrication and cryogenic/radiation testing services performed using facilities such as the Los Alamos Neutron Science Center, and US federal SBIR and program contracts from NASA, DARPA and the Department of Defense for development of high-temperature and radiation-tolerant SiC electronics. Government customers anchor the revenue base, while a network of regional rep firms (NWN, Wescom, Spectrum Sales, Micro Technology Group) and a global distribution agreement with RFMW (March 2025) form the commercial go-to-market.

CoolCAD serves the aerospace, automotive/EV, green energy, military and defense, data center, power generation and UV water purification verticals, where SiC's higher switching speed, voltage density and thermal performance enable smaller and more efficient power conversion and UV sensing systems than silicon alternatives. The company holds multiple US patents on SiC CMOS fabrication, UV photodetectors, etching processes and thermal management, is ISO 9001:2015 certified, and has published more than 100 peer-reviewed papers through its founder and team.
