1700V SiC MOSFET optimized for high-frequency, high-efficiency applications
Littelfuse has announced their first 1700V SiC MOSFET, the LSIC1MO170E1000, expanding its portfolio of SiC MOSFET devices. An important addition to the Littelfuse SiC MOSFET product offering, the LSIC1MO170E1000 is a powerful addition to the company’s 1200V SiC MOSFETS and Schottky diodes already released. End-users will benefit from more compact, energy-efficient systems and also from a […]
eGaN power transistor hits 97% efficiency at 500 kHz
The EPC2051 is a 100-V GaN transistor with a maximum RDS(on) of 25 mΩ and a 37-A pulsed output current for high efficiency power conversion in a tiny 1.1-mm2 footprint. Applications demanding higher efficiency and power density no longer have to choose between size and performance. The EPC2051 measures just 1.30×0.85 mm (1.1 mm2). Despite the small footprint, […]
SiC MOSFET structure reduces resistance and boosts energy efficiency in power devices
Hitachi Ltd. says it has developed a new kind of silicon-carbide-based MOSFET that has dramatically lower on resistance than comparable devices. The new MOSFET uses what Hitachi calls a TED-MOS structure, for Trench-etched DMOS-FET. Compared to conventional DMOS-FET (Double-diffused MOSFET) devices, the new structure is said to reduce electric field strength, an index of durability […]

Superjunction MOSFETs for PFC and flyback topologies handle 950 V
Higher density, low-power SMPS designs require high voltage MOSFETs in a growing number. Infineon Technologies AG announces new member of its CoolMOS P7 family, the 950 V CoolMOS P7 Superjunction MOSFET. It meets even the most rigorous design requirements: for lighting, smart meter, mobile charger, notebook adapter, AUX power supply and industrial SMPS applications. This […]
Next-gen 650V MOSFETs target data centers, UPS, industrial applications
Toshiba Electronic Devices & Storage Corporation has launched a new series of next-generation 650V power MOSFETs that are intended for use in server power supplies in data centers, solar (PV) power conditioners, uninterruptible power systems (UPS) and other industrial applications. The first device in the DTMOS VI series is the TK040N65Z, a 650V device that […]
The benefits of silicon carbide in dc/dc converters
Adil Salman from Wolfspeed recently shot a video with us covering a silicon carbide charging circuit demonstration. The charger used Wolfspeed SiC MOSFETs. It had two stages. One is a PFC (power factor correction) stage, the other is an LLC converter stage. If you were to try building a similar charger with silicon IGBTs, you […]

1,000 A to a welder through a MOSFET
Rehan Tahir from Infineon recently filmed a video with us covering a cool demonstration that develops a thousand amps for a welder. The point was to highlight an Infineon 1 kA board that actually targets applications powering the GPUs and next-generation CPUs that will need a thousand amps or more. The demo uses Infineon power […]
