Alpha and Omega has announced a double-side-cooled 100V 197A (25°C) mosfet in a 5 x 6mm DFN package. Called AONA66916, thermal resistance form the junction to the top and bottom surfaces is 0.5 and 0.55C/W respectively. “The top-exposed DFN 5×6 package shares the same footprint as AOS’ standard DFN 5×6 package, eliminating the need to modify existing PCB layouts,” said ...

Rohm has added a lineup of 600V super-junction mosfets in 6.5 x 7 x 1.66mm SOT-223-3 packaging. “In recent years, power supplies for lighting and motors for pumps are required to be smaller as devices become more sophisticated – spurring the demand for compact mosfets that are essential for switching operation,” said the company. “Generally, however, it has been difficult ...

SemiQ will be exhibiting its 1.2kV SOT-227 silicon carbide mosfet power modules at APEC, the Applied Power Electronics Conference, at the end of February. The modules come with or without a co-packaged Schottky diode, with current ratings between 30 and 113A, and on-resistance spanning 80mΩ to 20mΩ respectively (see table). The SOT-227 package is designed to be bolted to a ...

Vishay has introduced four ultra-fast 200V rectifier diodes: VS-1EAH02xM3 (1A) VS-2EAH02xM3 (2A), VS-3EAH02xM3 (3A) VS-5EAH02xM3 (5A) “Their low-profile DFN3820A housings provide a space-saving solution with high efficiency, predestined for commercial, industrial and especially automotive applications – they are each available as Vishay Automotive Grade, AEC-Q101 qualified versions,” according to distributor Rutronik, which is stocking the parts. Taking the 3A VS-3EAH02HM3 ...

Central Semiconductor has announced five 650V n-channel super-junction mosfets in TO-220FP packaging. They are: CDMSJ2204.7-650 (4.7A) CDMSJ2207.3-650 (7.3A) CDMSJ22010-650 (10A) CDMSJ22013.8-650 (13.8A) CDMSJ22029-650 (29A) “These super-junction mosfets extend efficiency for a variety of end applications,” according to Central marketing director Tom Donofrio. Additionally, “these pair well with Central’s fast rectifiers for power factor correction”.

Toshiba is in volume production of a photovoltaic output photocoupler with an enhanced open-circuit voltage suitable for gating high-voltage power MOSFETs commonly used in solid-state relays (SSRs). The TLX9910 photocoupler is primarily intended for use within SSR applications in automotive. However, it can equally be used in industrial applications, such as renewable energy. This combination enables high-voltage, high-current switching, which ...

Infineon has put 650V mosfet die from its CFD7A portfolio into a surface-mount package with “improved electrical performance over the well-known TO247 through-hole devices, thus enabling efficient energy utilisation in onboard chargers and dc-dc converters”, it said. ‘QDPAK TSC’ is a top-side-cooled package (see images) announced earlier this year and now registered with JEDEC – at the same time it ...

Toshiba has launched its first 30V n-channel common-drain dual mosfet, for controlling bi-directional power flow in USB-connected devices. The USB Power Delivery standard supports power levels from 5V 3A to 48V 5A, and allows swapping of the power supply and receiving side, requiring devices with USB charging to support bi-directional power. In developing a 30V common drain mosfet, called SSM10N961L, ...

Toshiba has launched a 200A 40V 0.66mΩmax automotive grade n-channel mosfet that can handle 600A pulses in a 7 x 8.44 x 2.3mm gull-wing package. “Automotive safety-critical applications such as steering, braking and autonomous driving systems generally require more devices than other systems to meet redundancy requirements. Here, a power mosfet with high current density is required due to the ...

Rohm has developed a range of five 100V dual mosfets for single-phase or three-phase bridges in fan motor drives. Four of them are dual n-channel in 5 x 6mm or 3.3 x 3.3mm packages, and one has one n-channel and one p-channel mosfet in the same 5 x 6mm package. “Recent years have seen a transition to higher voltages from ...
