Qorvo launches four 1200V silicon carbide modules in compact E1B package
Qorvo Inc of Greensboro, NC, USA (which provides core technologies and RF solutions for mobile, infrastructure and defense applications) has announced four 1200V silicon carbide (SiC) modules in a compact E1B package with low on-resistance RDS(on), namely the 19mΩ, 50A UHB50SC12E1BC3N and 9.4mΩ, 100A UHB100SC12E1BC3N half-bridge modules and the 70mΩ, 15A UFB15C12E1BC3N and 35mΩ, 25A UFB25SC12E1BC3N full-bridge modules. The highly efficient SiC modules are suitable for electric vehicle (EV) charging stations, energy storage, industrial power supplies and solar power applications.
“The modules in this new family can replace as many as four discrete SiC FETs, thus simplifying thermos-mechanical design as well as assembly,” says Ramanan Natarajan, director of product line marketing for Qorvo’s SiC Power Products business. “Our cascode technology also allows higher switching frequency operation, further reducing solution size by using smaller external components,” he adds. “For our customers, the high efficiency of these modules streamlines the power supply design process so they can focus on the design, layout, assembly, characterization and qualification of one module as opposed to numerous discrete components.”
Led by the 9.4mΩ UHB100SC12E1BC3N, these four SiC modules leverage Qorvo’s unique cascode configuration, which minimizes RDS(on) and switching losses to maximize efficiency, especially in soft-switching applications. Silver-sinter die attach reduces thermal resistance to as low as 0.23°C/W; when combined with the stacked die construction found in the ‘SC’ part numbers, power cycling performance is improved by 2x over comparable SiC power modules on the market, it is reckoned. Together, these characteristics contribute to superior thermal performance and reliability with the ease of use and power density of a highly integrated SiC power module, Qorvo adds.
