Electronic Specifier takes a look at the top 5 power products released in October 2025.
onsemi unveils vertical GaN semiconductors
As global energy demand surges from AI data centres, electric vehicles, and other energy intensive applications, onsemi has introduced vertical gallium nitride (vGaN) power semiconductors, setting a new benchmark for power density, efficiency, and ruggedness for these applications.
These next-generation GaN-on-GaN power semiconductors conduct current vertically through the compound semiconductor, enabling higher operating voltages and faster switching frequencies, leading to energy savings to deliver smaller and lighter systems across AI data centres, electric vehicles (EVs), renewable energy, and aerospace, defence and security.
CoolSiC MOSFETs enhance power density in high-power applications
High-power applications such as electric vehicle charging, battery energy storage systems, and commercial, construction, and agricultural vehicles (CAVs) are driving the demand for higher system-level power density and efficiency to meet increasing performance expectations. At the same time, these requirements introduce new design challenges, including reliable operation under harsh environmental conditions, robustness against transient overloads, and optimised overall system performance.
First radiation hardened buck controller with integrated gate driver
Infineon Technologies announces the industry’s first radiation-hardened (rad-hard) buck controller with an integrated gate drive. Designed for Point of Load (PoL) power rails in commercial space systems and other extreme environments, the new device is particularly well-suited for distributed satellite power systems and digital processing payloads, including FPGA and ASIC systems.
Automotive surge-protection Zener diodes in compact SOD-523 package
Toshiba expands its automotive-grade surge-protection Zener diode lineup with the launch of the XCEZ series. These new diodes are housed in a small and versatile SOD-523 package, making them particularly suitable for space-constrained applications such as in-vehicle Infotainment (IVI), advanced driver-assistance systems (ADAS), and battery management systems (BMS).
Pickering’s reed relay newly upgraded to 200W
Pickering Electronics, has upgraded its Series 68 high voltage reed relays to include a new variant supporting high power switching up to 200W. Previously available only in sister devices in the Series 67 family and the latest newly-released Series 600 relays, this highest power switch in the Pickering portfolio, rated up to an impressive 200W, is now available for 1 Form A configurations of Series 68, with a stand-off voltage of up to 8kV, and capable of switching up to 6kV.
