Toshiba Electronic Devices & Storage Corporation has expanded the lineup of 150V N-channel power MOSFETs with new six products that use the new generation process “U-MOSⅩ-H series.” Products in this series are suitable for the switching power supplies of industrial equipment such as data centers and communication base. The package of new products is a three-pin through hole type: TO-220 for “TK4R9E15Q5, TK7R2E15Q5 and TK9R6E15Q5” and TO-220SIS for “TK5R0A15Q5, TK7R4A15Q5 and TK9R7A15Q5.”
The new products use the U-MOSⅩ-H process to achieve low drain-source On-resistance. In particular, TK4R9E15Q5 features the excellent low drain-source On-resistance of 4.9mΩ (max). In addition, the new products uses high-speed diode (HSD) to improve reverse recovery characteristics, which are important for synchronous rectification applications, by reducing reverse recovery charge and faster reverse recovery time. Used in synchronous rectification applications, the new products reduce the power loss of switching power supplies and help improve efficiency.
The first product TPH9R00CQ5 which uses HSD, has approximately 74% less reverse recovery charge and approximately 44% faster reverse recovery time than Toshiba‘s existing product TPH9R00CQH, which does not use HSD. The U-MOSⅩ-H process using this HSD has applied to through hole type packages in addition to surface mount type packages.
The new products have reduced the drain source spike voltage generated between the drain and source when MOSFET is switching, helping to lower EMI in switching power supplies.
Toshiba will continue to promote the expansion of its power MOSFET lineup, which helps improve the efficiency of power supplies, thereby contributing to reducing the power consumption of equipment.
Applications
- Switching power supplies for communication equipment, etc. (high efficiency AC-DC converters, high efficiency DC-DC converters, etc.)
- Motor control equipment (motor drives, etc.)
Features

Electric drives are becoming increasingly prevalent in the boat and ship sector. At METSTRADE, Bosch Engineering is unveiling a newly developed, high-performance electrification solution for electrical systems with voltages of up to 800 volts, which further extends the potential use cases of electric drives in maritime applications while also raising system efficiency.
“With the latest generation of our electric motor and inverter with silicon carbide power modules, we offer a complete system that allows not only recreational boats but also larger sailing yachts and working boats to be operated with an efficient, quiet, yet still very powerful electric drive,” states Philip Kurek, who is responsible for off-highway and maritime solutions at Bosch Engineering.
The new electric motor SMG 230 is designed for system voltages of 400 to 800 volts. In an ideal voltage and temperature range, it offers a continuous power output of up to 200 kilowatts and around 250 newton meters of torque. Thanks to the 800-volt technology, the power density has also been increased significantly. The SMG 230 delivers 80 kilowatts more power than a comparable 400-volt machine with identical weight or, with the same level of performance, boasts more compact dimensions and a much lower weight.
The inverter with silicon carbide semiconductors, which is also designed for electrical voltages of up to 800 volts, is characterized by its impressive efficiency of more than 99 percent. The silicon carbide semiconductors in the power modules enable faster switching operations, meaning that significantly less energy is lost in the form of heat.
Bosch’s complete kit for the electrification of boat drives comprises electronic control units, inverters, electric motors, and transmissions for both 400- and 800-volt applications. This gives shipyards and system integrators maximum flexibility when adapting the electrification strategy to the respective requirements and allows them to integrate the relevant components quickly and easily into their ships. The system components are based on modern automotive technology and combine high robustness with utmost reliability. With its comprehensive kit for the electrification of ship drives, Bosch is making a crucial contribution to the ongoing reduction of greenhouse gas and noise emissions.

At this month’s IEEE Energy Conversion Congress and Expo (ECCE), Navitas Semiconductor introduced conference attendees to ‘IntelliWeave’ – an innovative patented new digital control technique for improving next generation AI data center power supply (PSU) efficiency.
In a world where ever-more energy is needed for the processing of artificial intelligence (AI) and cloud-based applications, minimizing power consumption has become a priority for data center architects and operators. Combining next-generation GaN and SiC semiconductors with new control technique strategies to power conversion plays a key role in achieving this goal.
IntelliWeave’s novel digital control enables highest system efficiencies with precision current sharing, ultra-fast dynamic response and minimal phase error. A patented dual-loop and dual-feed-forward interleaving control achieves absolute zero voltage switching (ZVS) across the full-load range to enable highest efficiencies.
The digital control for Critical Conduction Mode (CRM) interleaving Totem Pole Power Factor Control (PFC) enables 30% reduction in power losses compared to existing Continuous Conduction Mode (CCM) solutions. The digital control combined with high-power GaNSafe power ICs has been proven on a 500 kHz GaN-based interleaving 3.2 kW CrM PFC PSU operating at 99.3% peak efficiency including EMI filter loss.
Taking place in Phoenix, Arizona from October 20th to 24th, IEEE ECCE 2024 features both industry-driven and application-oriented technical sessions and brings together practicing engineers, researchers and other professionals for interactive and multidisciplinary discussions on the latest advances in various areas related to energy conversion.

Ideal Power Inc. announced the start of third-party automotive qualification and reliability testing of B-TRAN™ devices.
“This is a significant milestone in our commercialization roadmap as third-party automotive qualification and reliability testing of B-TRAN™ is now underway. Demonstration of compliance with automotive standards, the most stringent reliability standards for power semiconductor devices, is expected to accelerate the adoption of B-TRAN™ with large industrial customers as well as automotive OEMs and Tier 1 automotive suppliers,” said Dan Brdar, President and Chief Executive Officer of Ideal Power.
Ideal Power successfully performed a critical subset of reliability testing of packaged B-TRAN™ devices in its lab and at a third-party testing site to confirm readiness for third-party automotive qualification and reliability testing. This testing focused on the reliability of packaged B-TRAN™ devices in extreme environmental conditions and under high electrical and thermal stress as well as blocking voltage and shock testing.
All of the tested devices packaged by commercial packaging partner passed these tests indicating a robust B-TRAN™ packaging design. As a result, the Company engaged a third-party to commence full automotive qualification and reliability testing.
The automotive qualification and reliability testing includes a broader array of testing as required by automotive codes and standards utilizing specified parameters and a wide range of test conditions. The testing to achieve automotive qualification requires over a thousand packaged B-TRAN™ devices from multiple wafer runs.
The process includes tens of thousands of power cycles at various current levels, thermal cycling at extreme temperature and humidity levels, blocking voltage and shock and vibration testing, and visual inspection. These tests are designed to expose B-TRAN™ to conditions that are intended to accelerate failure mechanisms and demonstrate the long-term reliability of the devices. Successful completion of B-TRAN™ automotive qualification and reliability testing is expected in the first half of 2025.
