    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.

    Texas Instruments introduced the industry’s first 650V three-phase GaN IPM for 250W motor drive applications. The new GaN IPM addresses many of the design and performance compromises engineers typically face when designing major home appliances and heating, ventilation and air-conditioning (HVAC) systems.

    The DRV7308 GaN IPM enables more than 99% inverter efficiency, optimized acoustic performance, reduced solution size and lower system costs. It is on display at the Power Electronics, Intelligent Motion, Renewable Energy and Energy Management (PCIM) Conference, held June 11-13 in Nuremberg, Germany.

    “Designers of high-voltage home appliances and HVAC systems are striving to meet higher energy-efficiency standards to support environmental sustainability goals around the world,” said Nicole Navinsky, Motor Drives business unit manager at TI. “They are also addressing consumer demand for systems that are reliable, quiet and compact. With TI’s new GaN IPM, engineers can design motor driver systems that deliver all of these expectations and operates at peak efficiency.”

    Improve system efficiency and reliability with TI GaN

    Worldwide efficiency standards for appliances and HVAC systems such as SEER, MEPS, Energy Star and Top Runner are becoming increasingly stringent. The DRV7308 helps engineers meet these standards, leveraging GaN technology to deliver more than 99% efficiency and improve thermal performance, with 50% reduced power losses compared to existing solutions.

    In addition, the DRV7308 achieves industry-low dead time and low propagation delay, both less than 200ns, enabling higher pulse-width modulation (PWM) switching frequencies that reduce audible noise and system vibration. These advantages plus the higher power efficiency and integrated features of the DRV7308 also reduce motor heating, which can improve reliability and extend the lifetime of the system.

    To learn more about the benefits of GaN technology, read the white paper, “How three-phase integrated GaN technology maximizes motor-drive performance.”

    Advanced integration and high power density reduce solution size and costs

    Supporting the trend of more compact home appliances, the DRV7308 helps engineers develop smaller motor drive systems. Enabled by GaN technology, the new IPM delivers high power density in a 12mm-by-12mm package, making it the industry’s smallest IPM for 150W to 250W motor-drive applications.

    Because of its high efficiency, the DRV7308 eliminates the need for an external heatsink, resulting in motor drive inverter printed circuit board (PCB) size reduction of up to 55% compared to competing IPM solutions. The integration of a current sense amplifier, protection features and inverter stage further reduces solution size and cost.

    To learn about designing more efficient, compact motor systems, see the GaN IPM page on TI.com.

    Benefits:

    • Highest Creepage Distance Available for SiC Top Side Cooled Packages
    • Higher System Power Density with Optimized PCB Layouts
    • High Volume Manufacturing Capability with Surface Mount Footprint

    What’s New? Advantages of New Top Side Cooled Packages

    Most standard surface mount discrete power semiconductors remove heat through the bottom of the device by making direct contact with the power circuit board (PCB), which utilizes a heat sink or cooling plate attached underneath. This method is common across many different power electronics applications, particularly when size and weight requirements do not limit PCB mounting and heat sinks.

    Top side cooled (TSC) devices, on the other hand, dissipate heat through the top side of the package. Inside TSC packages, the die sits upside down in the upper portion of the package to allow heat to flow directly to the top surface. Generally, TSC devices are best suited for high-performance applications such as automotive and e-mobility systems where high-power densities, advanced thermal management solutions, and small footprints are essential. Within these applications, TSC devices help address cooling requirements by enabling maximum power dissipation and optimizing thermal performance.

    TSC designs also allow for dual-side usage of the PCB since the bottom board surface is no longer needed for the heatsink interface. Removing the heatsink from the thermal path not only creates an improved overall system thermal impedance; it also allows for automated assembly, which can increase manufacturing throughput for a more efficient and cost-effective solution.

    Navitas Semiconductor Released New Portfolio of Gen-3 ‘Fast’ 650V and 1200V SiC MOSFETs

    3 Min Read

    Navitas Semiconductor announced their new portfolio of Gen-3 ‘Fast’ (G3F) 650 V and 1,200 V SiC MOSFETs optimized for fastest switching speed, highest efficiency, and increased power density for applications such as AI data center power supplies, on-board chargers (OBCs), fast EV roadside super-chargers, and solar / energy-storage systems (ESS). The broad portfolio range covers industry-standard packages from D2PAK-7 to TO-247-4, designed for demanding, high-power, high-reliability applications.

    The G3F family is optimized for high-speed switching performance, resulting in 40% improvement to hard-switching figures-of-merits (FOMs) compared to competition in CCM TPPFC systems. This will enable increasing the wattage of next-generation AI power supply units (PSUs) up to 10 kW, and power per rack increase from 30 kW to 100-120 kW.

    The G3F GeneSiC MOSFETs  are developed using a proprietary ‘trench-assisted planar’ technology.  and offer better-than-trench MOSFET performance, while also providing superior robustness, manufacturability and cost than competition. G3F MOSFETs deliver high-efficiency with high-speed performance, enabling up to 25°C lower case temperature, and up to 3x longer life than SiC products from other vendors.

    The ‘trench-assisted planar’ technology enables an extremely low RDS(ON) increase versus temperature, which results in the lowest power losses across the complete operating range and offers up to 20% lower RDS(ON) under real-life operation  at high temperatures compared to competition.

    Additionally, all GeneSiC MOSFETs have the highest-published 100%-tested avalanche capability, 30% longer short-circuit withstand time, and tight threshold voltage distributions for easy paralleling, GeneSiC MOSFETs are ideal for high-power, fast-time-to-market applications.

    Navitas’ latest 4.5 kW high-power density AI Server PSU reference design in CRPS185 form-factor, showcases the 650 V-rated, 40mOhms G3F FETs for an Interleaved CCM TP PFC topology. Alongside the GaNSafe™ Power ICs in the LLC stage, a power density of 138 W/inch3 and peak efficiency above 97% is realized, which comfortably achieves ‘Titanium Plus’ efficiency standards, now mandatory in Europe.

    For the EV market, 1,200 V/34 mOhm (G3F34MT12K) G3F FETs enable Navitas’ new 22 kW, 800V Bi-Directional OBC and 3KW DC-DC converter to achieve a superior power density of 3,5 kW/L and a peak efficiency of 95.5%.

    “G3F sets a new standard for efficient, cool-running SiC performance, coupled with high reliability and robustness for high-power, high-stress systems,” noted Dr. Sid Sundaresan, Senior Vice President of SiC Technology and Operations. “We’re pushing the boundaries of SiC, with up to 600 kHz switching speeds, and hard-switching figures-of-merit up to 40% better than competition.”

    Cambridge GaN Devices and Qorvo® Partner to Develop a Reference Design and Evaluation Kit for Motor Control

    3 Min Read

    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.
