Vishay Intertechnology, Inc. introduced a new 80 V symmetric dual n-channel power MOSFET that combines high and low side TrenchFET® Gen IV MOSFETs in a single 3.3 mm by 3.3 mm PowerPAIR® 3x3FS package. 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. For increased efficiency in high frequency switching applications, the SiZF4800LDT offers a low on-resistance times gate charge — a key figure of merit (FOM) for MOSFETs used in power conversion applications — of 131mW*nC and on-resistance times gain-drain charge
The device’s flip-chip technology enhances thermal dissipation — resulting in 54 % lower thermal resistance compared to competing MOSFETs. The SiZF4800LDT’s combination of low on-resistance and thermal resistance results in a continuous drain current of 36 A, which is 38 % higher than the closest competing device. The MOSFET features a unique pin configuration that enables a simplified PCB layout and supports shortened switching loops to minimize parasitic inductance. The SiZF4800LDT is 100 % Rg- and UIS-tested, RoHS-compliant, and halogen-free.

Vitesco Technologies is preparing the series application of its High Voltage Box. The modular system makes charging, converting and distributing electricity in electric vehicles cheaper by integrating several functions in one unit, depending on the design.
This includes the vehicle On-Board Charger for AC charging on the grid with up to 22 kW of charging power, a DC current converter providing the current for the 12 V vehicle net, and power electronics which distribute high voltage power in the vehicle and facilitate fast DC-charging with up to 800 V.
Owed to the high level of mechatronic integration, the High Voltage Box has smaller space requirements to the vehicle while increasing the total system reliability in comparison to individual devices. State-of-the art silicon carbide (SiC) semiconductors boost charging efficiency to over 95 percent which lowers the vehicle owner’s electricity bill. This efficiency level is particularly beneficial for car owners because electric vehicles are frequently charged on the grid.
Due to the high AC charging rate of up to 22 kW the High Voltage Box charges the car with 200 km of range in under two hours. DC high-power charging with up to 800 V achieves the same range in 12 minutes. The sophisticated power electronics ensure that this system offers electrical safety as well as efficiency.
On a day-to-day level, charging, energy conversion and power distribution are just as relevant for a driver’s satisfaction with a vehicle as driving itself is. With our High Voltage Box, we integrate these core tasks of energy management into one efficient and compact unit. This integration makes electrification on a large scale and at low cost easier.
Thomas Stierle, Member of the Executive Board and head of the Electrification Solutions division of Vitesco Technologies
Today, the so-called On-Board Charger (OBC) for charging with alternating current (AC) on the grid is a separate device in the vehicle. This OBC inverts grid power to direct current (DC) that can be fed to the high voltage battery. Another separate device is the DC/DC converter which provides direct current from the high voltage battery to the 12 V power net – or it boosts 12 V to high voltage DC. A power electronics unit distributes high voltage current within the vehicle (hence: Power Distribution Unit, PDU). In addition, these electronics can be designed to allow DC charging with up to 800 V at high power charging points. All those components need to be connected, they require a housing, installation space, and cooling.
The modular and scalable High Voltage Box makes it easier to cover two or more of these functions with a single device. SiC technology is used to minimize the conversion losses of the unit:
A high level of efficiency brings the car owner’s electricity bill down and contributes to sustainability.
Christian Preis, Head of Base Development Energy Transformation at Vitesco Technologies
Within the modular design Vitesco Technologies covers all relevant European and worldwide grid topologies. The High Voltage Box was developed to support modular vehicle adaptation for the global market. At the same time, Vitesco Technologies is driving new functions ahead. The High Voltage Box for one of the two series applications will already function bidirectionally so that it can supply alternating current with 230 V from the DC battery current when this is required.
This puts vehicle owners in the comfortable position to make versatile use of their large battery. For instance, if they wish to use power tools far away from the grid, or if they want to feed electricity to the grid which they have charged earlier from their own photovoltaic system. “In the future, this option to stabilize the grid will continue to gain importance “, Preis adds. The company’s experts are advancing the necessary standard for this in key committees and are thus part of the decision-making process about development trends.
In the future the High Voltage Box with bidirectional function can also make it possible to power a whole house from the High Voltage Battery during a blackout. This is an option because batteries in vehicles have a much bigger capacity than most of the batteries typically installed in private homes.

Infineon Technologies AG introduced a new product family of Solid-State Isolators to achieve faster and more reliable circuit switching with protection features not available in optical-based solid state relays (SSR). The isolators use coreless transformer technology and support 20 times greater energy transfer with both current and temperature protection contributing to a higher reliability and lower cost of ownership.
The new solid-state isolators allow driving the gates of Infineon’s MOS-controlled power transistors OptiMOS ™ and CoolMOS™ to reduce power dissipation of up to 70 percent of todays’ solid-state relays using SCR (silicon-controlled rectifier) and Triac switches.
Infineon’s solid-state isolators enable custom solid-state relays capable of controlling loads more than 1000 V and 100 A. Improved performance and reliability make coreless transformer technology ideal for applications in advanced battery management, energy storage, renewable energy systems, as well as industrial and building automation system applications. With Infineon’s solid-state isolator drivers, engineers can further improve the efficiency of electronic and electromechanical systems.
“Implementing coreless transformers in solid-state isolators and relays is truly a game-changer for power engineers; it provides 50 times lower RDS (on) than existing optically controlled solutions. This enables their use in higher-voltage and higher power applications,” said Davide Giacomini, Marketing Director for the Green Industrial Power Division at Infineon Technologies.
When matched with Infineon’s CoolMOS S7 switch, the isolator drivers enable switching designs with a much lower resistance compared to optically driven solid-state solutions. This translates to longer lifespans and lower cost of ownership in system designs. As with all solid-state isolators, the devices also offer superior performance compared to electromagnetic relays, including 40 percent lower turn-on power and increased reliability due to elimination of moving parts.
The family of devices is designed to be compatible with Infineon’s broad switching portfolio including Infineon’s CoolMOS S7, OptiMOS TM and linear FET portfolios.
