With a high power density, Infineon’s CoolSiC MOSFETs 1200 V can reduce losses by 50 percent and provide ~2 percent additional energy without increasing the battery size, which is especially beneficial for high-performance, lightweight, and compact energy storage solutions. FOXESS’ H3PRO 15 kW-30 kW energy storage series uses Infineon’s CoolSiC MOSFETs 1200 V for all models. Thanks to Infineon’s excellent performance, the H3PRO series has achieved an efficiency of up to 98.1 percent and excellent EMC performance; with superior performance and reliability, the H3PRO series has seen rapid sales growth in the global market.
Infineon’s TRENCHSTOP IGBT7 H7 650 V / 1200 V series has lower losses and helps improve the overall efficiency and power density of inverters. In high-power inverter projects, high-current mold packaged discrete devices with current handling capability above 100 A can reduce the number of IGBTs in parallel and replace the IGBT module solution, further improving system reliability and reducing costs; in addition, the H7 series has become an industry benchmark for its high-quality performance and greater resistance to humidity.
At present, FOXESS’ main industrial and commercial model, the R Series 75-110 kW, redefines the overall design of the 100 kW model by using IGBT7 H7 series discretes, and the efficiency of the whole machine can reach up to 98.6 percent. Thanks to the low power loss and high power density of the IGBT7 H7 series in discrete packages, technical problems such as current sharing in the paralleling process can be simplified and optimized.
Every power device needs a driver, and the right driver can make the design a lot easier. Infineon offers more than 500 EiceDRIVER gate drivers with typical output currents of 0.1 A~18 A and comprehensive protection functions including fast short-circuit protection (DESAT), active Miller clamp, shoot-through protection, fault reporting, shutdown, and overcurrent protection, suitable for all power devices including CoolSiC and IGBTs.

The aviation industry’s requirements for the latest, most efficient and lowest-emission aircraft is propelled by an overarching goal towards sustainability and decarbonization. To satisfy these goals, aviation power systems developers are transitioning to electric actuation systems as the trend towards More Electric Aircraft (MEA) continues to grow.
To provide the aviation industry with a comprehensive electric actuation solution, Microchip Technology announced a new integrated actuation power solution that combines companion gate driver boards with the expansive Hybrid Power Drive (HPD) modules in silicon carbide or silicon technology with a power range of 5 kVA to 20 kVA.
The new integrated actuation power solution maintains the same footprint regardless of the power output. The companion gate driver boards are designed to be integrated with Microchip’s HPD modules to provide an all-in-one motor drive solution for the electrification of systems such as flight controls, braking and landing gear. Microchip’s power solutions are designed to scale based on the requirements of the end application, from smaller actuation systems for drones to high-power actuation systems for Electric Vertical Take-Off and Landing (eVTOL) aircraft, MEA and all-electric aircraft.
“We developed the companion gate driver boards to be used with our existing HPD modules to bring to market a plug-and-play power solution for MEA,” said Leon Gross, vice president of Microchip’s discrete product group. “With this solution, customers no longer need to design and develop their own drive circuitry, which can reduce design time, resources and cost.”
These high-reliability devices are tested to conditions outlined in DO-160, “Environmental Conditions and Test Procedures for Airborne Equipment.” There are multiple protection features including shoot-through detection, short circuit protection, desaturation protection, Under Voltage Lock Out (UVLO) and active miller clamping.
The gate driver boards are designed to be driven with external PWM signals based on Low Voltage Differential Signaling (LVDS) compliant with TIA/EIA-644 for low Electromagnetic Interference (EMI) and good noise immunity. The gate driver board provides differential outputs for telemetry signals like DC bus current, phase current and solenoid current by taking feedback from shunts present in the HPD module and DC bus voltage. It also provides direct output of two PT1000 temperature sensors available in the HPD power module.
The companion gate driver boards are low-weight, low-profile and compact solutions to optimize size and power efficiency of actuation systems. The gate drivers are designed to operate throughout the temperature range of −55°C to +110°C, which is critical for aviation applications that are often exposed to harsh environments.
The isolated companion gate driver boards only require a single 15V DC input for the control and drive circuit; additional voltages needed can be generated on the card. This significantly reduces the number of system components and simplifies system cabling.
Microchip provides comprehensive solutions for MEA by integrating power products with FPGAs, microcontrollers, security, memory and timing. Microchip’s solutions are designed to help customers speed up their development, reduce costs and get to market faster.

For power conversion in industrial and telecom applications, the Vishay Siliconix SiZF4800LDT increases power density and efficiency, while enhancing thermal performance, reducing component counts, and simplifying designs.
This dual MOSFET can be used in place of two discrete devices typically specified in the PowerPAK 1212 package — saving 50 % board space. The device provides designers with a space-saving solution for synchronous buck converters, point of load (POL) converters, and half- and full-bridge power stages for DC/DC converters in radio base stations, industrial motor drives, welding equipment, and power tools. In these applications, the high and low side MOSFETs of the SiZF4800LDT form an optimized combination for 50 % duty cycles, while its logic level turn-on at 4.5 V simplifies circuit driving.
To increase power density, the MOSFET offers best in class on-resistance down to 18.5 mW typical at 4.5 V. This is 16 % lower than the closest competing device in the same package dimensions.

Nexperia is once again bringing its product innovations to APEC and today announced the release of several new MOSFETs to further broaden its range of discrete switching solutions for use in various applications across multiple end markets.
This release includes 100 V application specific MOSFETs (ASFETs) for PoE, eFuse and relay replacement in 60% smaller DFN2020 packaging, and 40 V NextPowerS3 MOSFETs with improved electromagnetic compatibility (EMC) performance.
PoE switches typically have up to 48 ports, each requiring 2 MOSFETs for protection. With up to 96 MOSFETs on a single PCB, any reduction in device footprint is attractive. For this reason, Nexperia has released 100 V PoE ASFETs in 2 mm x 2 mm DFN2020 packaging which occupies 60% less space than previous versions in LFPAK33 packaging.
A critical function of these devices is to protect PoE ports by limiting inrush currents while safely managing fault conditions. To manage this scenario, Nexperia has enhanced the safe operating area (SOA) of these devices by up to 3x with only a minimal increase in RDS(on). These ASFETs are also suitable for battery management, Wi-Fi hotspot, 5G picocell and CCTV applications and can serve as replacements for mechanical relays in smart thermostats, for example.
EMC-related issues caused by MOSFET switching usually only emerge late in the product development life cycle and resolving them can incur additional R&D costs and delay market release. Typical solutions include using significantly more expensive MOSFETs with lower RDS(on) (to slow down switching and absorb excessive voltage ringing) or to fit an external capacitive snubber circuit but this approach has the disadvantage of increasing component count.
Nexperia has optimized its 40 V NextPowerS3 MOSFETs to offer similar EMC performance as that which can be achieved using an external snubber circuit, while also offering higher efficiency. These MOSFETs are suitable for use in switching converters and motor controllers across various applications and are available in LFPAK56 packaging.
“By introducing these latest additions to our range of discrete FET solutions at APEC 2024, Nexperia showcases how we leverage our expertise in R&D to deliver optimized solutions. Both our new 100 V PoE ASFETs as well as improved EMC performance in our 40 V NextPowerS3 MOSFETs demonstrate our commitment to supporting engineers in overcoming challenges across diverse applications. These innovations underscore Nexperia’s dedication to providing efficient, compact, and reliable solutions that empower our customers to succeed in today’s ever-evolving market,” says Chris Boyce, MOSFET Marketing & Product Group Director at Nexperia.
