Toshiba Electronic Devices & Storage Corporation launched 650V N-channel power MOSFETs “TK068N65Z5, TK095E65Z5, TK095A65Z5, TK095V65Z5, TK115E65Z5, TK115A65Z5, TK115V65Z5 and TK115N65Z5” and added them to the lineup of Toshiba’s latest-generation DTMOSVI series with high-speed diodes (DTMOSVI (HSD)) that uses super junction structure and is suitable for high-efficiency switching power supplies for data centers and power conditioners for photovoltaic generators. Packages of the new products are TO-247, TO-220SIS, TO-220 and DFN8×8.
The new products with the DTMOSVI (HSD) process use high-speed diodes to improve the reverse recovery characteristics important for bridge circuit and inverter circuit applications. Against Toshiba’s existing product TK090A65Z of the standard type DTMOSVI, the new product TK095A65Z5 achieves an approximately 65% reduction in reverse recovery time (trr), and an approximately 88% reduction in reverse recovery charge (Qrr) (measurement conditions: -dIDR/dt=100A/μs).
In addition, the DTMOSVI (HSD) process improves on the reverse recovery characteristics of Toshiba’s existing products DTMOSIV series with high-speed diodes (DTMOSIV (HSD)), and has a lower drain cut-off current at high temperatures. Furthermore, the figure of merit “drain-source On-resistance × gate-drain charge” is also lower.
The high temperature drain cut-off current of the new product TK095A65Z5 is approximately 91% lower, and the drain-source On-resistance × gate-drain charge approximately 70% lower, than in Toshiba’s existing product TK35A65W5. This advance will cut equipment power loss and help to improve efficiency.
A reference design, “1.6kW Server Power Supply (Upgraded)“, that uses the same series product TK095N65Z5 is available on Toshiba’s website.
Toshiba also offers tools that support circuit design for switching power supplies. Alongside the G0 SPICE model, which verifies circuit function in a short time, highly accurate G2 SPICE models that accurately reproduce transient characteristics are now available.
Toshiba also will continue to expand its lineup of the DTMOSVI series. This will enhance switching power supply efficiency, contributing to energy-saving equipment.

An explanation of the use of non-GAAP financial measures and a reconciliation of Aehr’s non-GAAP financial measures to the most directly comparable GAAP financial measures can be found in the accompanying tables.
Gayn Erickson, President and CEO of Aehr Test Systems, commented:
“Our full-year revenue and net income results exceeded our previously provided guidance and surpassed analyst consensus. Although we saw customer pushouts of silicon carbide devices due to slower electric vehicle (EV) demand in the second half of our fiscal year, we achieved another record year for annual revenue for Aehr.
“Wafer level test and burn-in of silicon carbide power semiconductors used in EVs was a key driver of our business in the last year, and we anticipate silicon carbide will continue to be a key contributor to revenue in the current fiscal year and beyond. To that point, we announced today that we received $12.7 million in orders from one of our silicon carbide test and burn-in customers for FOX WaferPak™ full wafer Contactors to support production of silicon carbide power devices for electric vehicles to be delivered over the next three months.
“The silicon carbide market continues to be an enormous opportunity for Aehr as we see more auto suppliers committed to silicon carbide in their EVs, as well as roadmaps that are based on modules for their electric motor power inverters. By 2030, battery EVs are forecasted to more than triple last year’s sales to 30 million or 30% of total vehicles manufactured worldwide.
“We remain actively engaged with a significant number of new silicon carbide device and module suppliers and seek to meet their anticipated capacity coming online beginning in 2025. We are also seeing growing demand for silicon carbide devices beyond the EV market, such as solar, data center, and other industrial applications for power conversion. We believe we are well positioned to continue to grow our business in silicon carbide, and we expect to receive first orders from a significant number of additional silicon carbide customers by the end of this fiscal year.
“We are also seeing traction with several emerging opportunities for our test and burn-in solutions in new target markets and expect bookings and revenue across a much broader range of customers and markets this fiscal year.
“One of the key new market opportunities we are focusing on is the growing demand for Artificial Intelligence (AI) processor test and burn-in at both the wafer level and the packaged part level.
“We are currently working with an AI accelerator company and have secured a commitment from them to evaluate our FOX solution for use in production wafer level burn-in of their high-power processors. Upon successful demonstration of wafer level test results and throughput, we expect they will utilize our new high-power FOX-XP systems for production of their next generation AI processors, starting this fiscal year.
“We also announced today in a separate press release our acquisition of Incal Technology, a manufacturer of highly acclaimed reliability test and burn-in solutions of a wide range of semiconductor devices and markets, with a new product family of ultra-high-power test solutions for AI accelerators, graphics & network processors, and high-performance computing processors. We believe that between wafer level and package part, the reliability test and production burn-in market for AI processors exceeds $100 million annually, and with this combined product portfolio we believe we have the opportunity to capture a meaningful share of the market this fiscal year.
“This past year we announced our first order for a FOX wafer level test and burn-in system for gallium nitride (GaN) devices. While silicon carbide will be the semiconductor material of choice for EV traction inverters, GaN is expected to gain significant penetration in the on-board charging market as well as other automotive, solar, and data center power conversion applications. We are working with several of the GaN market leaders, and received a significant number of WaferPak orders throughout the year for gallium nitride reliability test and qualification. We have now received our first forecasts for wafer level production burn-in systems to be delivered during this fiscal year. We continue to be encouraged by this market and believe it will be significant in market size for semiconductors and has the potential to be a solid market opportunity for Aehr’s solutions.
“Within the silicon photonics market, we shipped the first order from a major silicon photonics customer for the new high-power configuration of our FOX-XP system this last fiscal year. This new configuration expands our market opportunity by enabling cost-effective volume production test of wafers of next-generation photonic ICs that are targeted for use in the new optical I/O or co-packaged optics market. Nvidia, AMD, and Intel have all discussed the potential for adding optical chip-to-chip communication for performance improvement and power savings for AI processors and High-Performance Computing chips.
“Looking ahead, we believe Aehr has significant opportunities for growth in fiscal 2025 and beyond with our industry-leading product portfolio, and we look forward to updating you on our progress throughout the year as we seek to capitalize on these exciting new opportunities.”
Fiscal 2025 Financial Guidance:
For the fiscal year ending May 30, 2025, Aehr expects total revenue of at least $70 million and net profit before taxes of at least 10% of revenue.

Nexperia released 650V ultra- and hyperfast recovery rectifiers in D2PAK Real-2-Pin (R2P) packaging for use in various automotive, industrial and consumer applications including charging adapters, photovoltaic (PV), inverters, servers and switched mode power supplies (SMPS).
Combining planar die technology with a state-of-the-art junction termination (JTE) design, these rectifiers offer high power density, fast switching times with soft recovery and excellent reliability. They are encapsulated in a D2PAK Real-2-Pin Package (SOT8018), which offers the same package outline as the standard D2PAK package but has only two pins instead of three (the middle cathode pin has been removed). This increases the pin-to-pin distance from 1.25mm to over 4mm, which allows to meet the creepage and clearance requirements stated in the IEC 60664 standard.
“These recovery rectifiers further demonstrate Nexperia’s expertise in the field of semiconductor device packaging” according to Frank Matschullat, Head of Product Group Power Bipolar Discretes at Nexperia. “By taking the innovative step of removing the cathode pin from a standard D2PAK package, Nexperia has created a Real-2-Pin package that can meet the creepage and clearance requirements, in particular for high voltage automotive applications.”

Efficient Power Conversion (EPC) announced that it has moved one step closer to achieving preeminence in the gallium nitride (GaN) power semiconductor industry, as its intellectual property rights to this revolutionary technology were upheld for the third time in three months. The next-generation wide bandgap semiconductors developed by EPC are essential to artificial intelligence (AI), satellites, fast chargers, lidar, humanoid robots and many other transformational technologies.
The U.S. International Trade Commission (ITC) found two of EPC’s key patents valid and one, the Company’s foundational patent, infringed by Innoscience (Zhuhai) Technology Co., Ltd. and its affiliate, Innoscience America, Inc. The ITC’s recommendation comes on the heels of two recent decisions from the China National Intellectual Property Administration (CNIPA), which similarly validated EPC’s counterpart patents in China. The ITC initial determination is a significant milestone in solidifying EPC’s leadership in wide bandgap semiconductors and could lead to a ban later this year on importation of Innoscience’s infringing products into the United States.
“The ITC’s finding that Innoscience uses our patented technology without authorization puts EPC in an enviable position, as U.S. and Chinese regulatory bodies have upheld the validity of our patents,” said Alex Lidow, CEO and Co-Founder of EPC.
“The Commission’s recommendations validate nearly two decades of hard work, resources and R&D that went into developing EPC’s uniquely valuable intellectual property portfolio,” Dr. Lidow added.
Over the last 15 years, EPC has capitalized on its first-mover advantage to develop a broad portfolio of over 200 GaN-related patents and over 150 products, which include its rapidly growing family of integrated circuits, automotive qualified and radiation hardened devices.
Compared with traditional silicon-based power devices, GaN represents a significant leap, with higher efficiency, faster switching speeds, smaller size and lower cost. GaN power devices are integral to self-driving vehicles, medical and communications devices, next-generation rapid chargers, drones, satellites, data centers, e-bikes, solar power systems and humanoid robots, among many other applications. Most notably, EPC’s cutting-edge semiconductors are central to powering the AI revolution by significantly freeing up space for extra computing power while simultaneously reducing energy consumption.
The ITC’s preliminary ruling found both U.S. patents that EPC asserted against Innoscience valid. It also found “infringement [by Innoscience] of U.S. Patent No. 8,350,294,” EPC’s foundational patent used broadly across multiple industries. The second EPC patent, U.S. Patent No. 8,404,508, was found valid, but not infringed by Innoscience. The Commission’s final determination is expected to be issued on November 5, 2024.
