Qorvo® announced the industry’s first 4 milliohm silicon carbide (SiC) junction field effect transistor (JFET) in a TOLL package. It was designed for circuit protection applications including solid-state circuit breakers, where low resistance, superior thermal performance, small size and reliability are paramount.
With RDS(on) of just 4 milliohm, the UJ4N075004L8S offers the industry’s lowest on-resistance among the 650V to 750V class of power devices in standard discrete packages. This low RDS(on) drives significant reductions in heat generation and, when coupled with a compact TOLL package, enables a solution size that is 40% smaller than competing devices in TO-263 packages.
This small solution size supports the space-limited dimensions of today’s electromechanical circuit breakers and operates without the need for elaborate cooling systems, accelerating the transition from electromechanical circuit breakers to semiconductor-based solid-state circuit breakers (SSCBs).
“With the introduction of the UJ4N075004L8S, Qorvo continues to lead the way in SiC power innovation, catalyzing the emergence of applications such as circuit protection with ultra-low RDS(on) FET offerings in very small footprints,” said Ramanan Natarajan, director of product line marketing for Qorvo’s SiC Power Products business. “The SSCB market is growing rapidly, and Qorvo’s newest product marks a significant milestone in the evolution of the technology.”
Qorvo’s JFETs are highly robust devices well suited to meet the challenges of circuit protection, providing the ability to turn off at very high inrush currents during circuit faults. Qorvo’s newest JFET can also withstand high instantaneous junction temperatures without experiencing degradation or parametric drift. The normally-on nature of the JFET lends itself to seamless integration into systems where the switch is in the on-state by default and in turn-off state under fault conditions.
The UJ4N075004L8S is now available for sampling and will enter full production in Q4 2024, accompanied by additional JFET options, including 750V with 5 milliohm and 1200V with 8 milliohm ratings, all in TO-247 packaging.

Cambridge GaN Devices is partnering with Qorvo® to develop a reference design and evaluation kit (EVK) that showcases GaN for motor control applications. CGD aims to speed the use of GaN power ICs in BLDC and PMSM applications, resulting in higher power, highly efficient, compact and reliable systems. Qorvo is building an EVK for its PAC5556A motor/control IC that is powered by CGD’s ICeGaN™ (IC-enhanced GaN) technology.
GIORGIA LONGOBARDI | CEO, CGD
“Because ICeGaN – unlike other GaN implementations from other companies – integrates the interface circuitry but not the controller together with the GaN HEMT, it is simple to combine with highly integrated motor controller and drive ICs such as Qorvo’s PAC5556A 600 V High Performance BLDC / PMSM Motor Controller and Driver. We are delighted to partner with Qorvo to enable motor controller and driver applications to enjoy the benefits of GaN power.”JEFF STRANG | GENERAL MANAGER, POWER MANAGEMENT BUSINESS UNIT, QORVO
“Wide bandgap semiconductors such as GaN and SiC are being actively considered in various motor control applications for the power density and efficiency benefits they bring. CGD’s ICeGaN technology offers ease of use and reliability, two crucial factors for motor control and drive designers. We are excited to see the reaction of design engineers when they experience the power of GaN combined with our highly integrated PAC5556A 600V BLDC motor control solution.”GaN brings a variety of benefits, primarily lower losses, which results in higher efficiency, leading to increased power availability and less heat. This reduces the need for complex, bulky, and costly thermal management solutions, resulting in smaller, more powerful systems that have a longer life. GaN also delivers higher torque at low speeds and, therefore, more accurate control. Also, GaN allows high-speed switching, which can reduce audible noise, which is especially valued for domestic items such as ceiling fans, heat pumps, and refrigerators.
In addition to being easy to use, ICeGaN offers several other significant benefits over other GaN devices. The gate drive voltage of ICeGaN is compatible with IGBTs. Because ICeGaN integrates the Miller clamp within the GaN IC, a negative Turn-Off voltage is not required, and low-cost current drivers can be used. Finally, ICeGaN includes a useful current sense function, simplifying circuit design and reducing BOM.
The reference design is available today, and EVK RD5556GaN will be available for purchase in Q324. It will also be shown on CGD’s booth Hall 7 643 at the PCIM exhibition in Nuremberg, Germany, 11-13 June. Qorvo will also exhibit at PCIM, on booth Hall 7 406.

Qorvo® announced four 1200V silicon carbide (SiC) modules – two half-bridge and two full-bridge – in a compact E1B package with RDS(on) starting at 9.4mΩ. These highly efficient SiC modules are excellent solutions 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 thermomechanical design as well as assembly. Our cascode technology also allows higher switching frequency operation, further reducing solution size by using smaller external components,” said Ramanan Natarajan, director of product line marketing for Qorvo’s SiC Power Products business.
“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.
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.
The table below provides a snapshot of Qorvo’s new 1200V SiC module family:
