DESCRIPTION
The UnitedSiC UJ4C and UJ4SC, UF3C and UF3SC series of silicon carbide FETs are based on a unique cascode configuration, where a high performance SiC fast JFET is co-packaged with a cascode optimized Si-MOSFET to produce the only standard gate drive SiC device in the market today. The UJ4C & UJ3C series are built for “ease of use” and the perfect solution when upgrading from an existing silicon-based device. The UJ4SC & UF3SC series provides faster switching speed and lower switching losses, and available in standard thru-hole (including Kelvin) and surface mount package options.

UnitedSiC debuted its first SiC FET device selection tool, the FET-Jet Calculator. The on-line tool helps power designers evaluate UnitedSiC devices in a variety of circuit topologies and focus in on the most promising solutions to make design decisions quickly and confidently. In addition, 9 new 750V Gen 4 devices were introduced, including the industry’s lowest RDS(on) SiC FET specified at 6mohms, half the value of its nearest competitor. On November 3, 2021, Qorvo announced the acquisition of UnitedSiC, with UnitedSiC becoming part of Qorvo’s Infrastructure & Defense Products (IDP) business. The UnitedSiC technology, together with Qorvo’s complementary Programmable Power Management products and world-class supply chain capabilities, will enable UnitedSiC to deliver superior levels of power efficiency in the most advanced applications.

STRONG FUTURE FOR SiC
Customers around the world are now using the UnitedSiC FET, JFET and Schottky diode devices in new electric vehicle (EV) chargers, AC-DC and DC-DC power supplies, solid-state circuit breakers, variable speed motor drives and solar PV inverters. As a result, these SiC devices are enabling our customers to achieve superior end-product performance, assuring success in their end markets.
