MOSFETS
What is the MOSFET body diode?
Unlike virtually every other active device, the power MOSFET is unusual in that its schematic symbol includes a parasitic device – the body diode. The body diode is intrinsic to the device’s structure. It remains despite a number of fundamental changes in power MOSFET structure and device designs including the two most common types today […]
N-channel MOSFETs with low on-resistance target mobile devices
Toshiba America Electronic Components, Inc. (TAEC)* has expanded its lineup of small, low on-resistance MOSFETs with the addition of the SSM6K513NU and SSM6K514NU. The new N-channel MOSFETs feature industry-leading[1] low on-resistance, and are suited for use as load switches in mobile devices such as smartphones and tablets. The 30V SSM6K513NU and 40V SSM6K514NU utilize Toshiba’s latest U-MOS […]
150-V MOSFETs offer 25% lower R DS(on) in SuperSO8 package
Aiming at high-efficiency designs and applications, Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) introduces the OptiMOS™ 5 150 V portfolio. This product family further expands the industry-leading OptiMOS 5 generation of power MOSFETs.

1 kV SiC MOSFET optimized for charging station use
Wolfspeed, a Cree Company and a leader in silicon carbide (SiC) power products, has introduced a 1000V MOSFET that enables a reduction in overall system cost, while improving system efficiency and decreasing system size. The new MOSFET, specially optimized for fast charging and industrial power supplies, enables a 30 percent reduction in component count while […]
New technique cuts costs of SiC high-voltage switches
Connecting several silicon-carbide MOSFETs in series may be a relatively inexpensive way of fielding high-performance power switches. So say researchers at North Carolina State University’s FREEDM Systems Center. The topology for the new power switches is called the FREEDM Super-Cascode. It combines 12 smaller SiC power MOSFETs in series to reach a power rating of […]
SuperFET III MOSFETs sport 44% lower RDS(on)
Fairchild Semiconductor, now part of ON Semiconductor), today introduced its SuperFET III family of 650V N-channel MOSFETs, the company’s new generation of MOSFETs that meet the higher power density, system efficiency and exceptional reliability requirements of the latest telecom, server, electric vehicle (EV) charger and solar products. The SuperFET III MOSFET family combines best-in-class reliability, low EMI, excellent […]
800-V MOSFETs incorporate ESD protection
Infineon Technologies AG introduces the 800 V CoolMOS™ P7 series. Based on the superjunction technology, this 800 V MOSFET combines best-in-class performance with exceptional ease-of-use. This new product family is a perfect fit for low power SMPS applications, fully addressing market needs in performance, ease of design, and price/performance ratio. It mainly focuses on flyback […]
N-channel MOSFET handles 100 V/160 A in automotive applications
Toshiba America Electronic Components, Inc. (TAEC) today announced the expansion of its lineup of automotive N-channel power MOSFETs with the addition of a new 100V, 160A device: the TK160F10N1L.
