Toshiba is claiming better improved on-resistance and gate charge for its third generation of industrial 650V enhancement-mode silicon carbide mosfets. The “third generation SiC process optimises the cell structures used in second-generation devices,” according to the company. “As a result, the product of Rds(on) and Qg, that represents both static and dynamic losses, has improved by about 80%”. In common ...

Schaffner has added the C14/C20 IEC dual locking power connector to its IEC range offering a way to prevent accidental disconnection in data-centres, PDUs, servers, industrial equipment, medical devices, audio/broadcast and other critical power systems. The C14/C20 IEC dual locking connector was designed to enhance Schaffner’s locking connector functionality with two locking mechanisms incorporated into one combined connector. This ensures ...

Saelig has introduced the ed-k DPG Power Choke Tester family – a series of  measurement instruments for inductive power components, using currents up to 4kA and pulse energy up to 7.7kJ. The DPG series uses a large-signal impulse measuring method to provide a complete inductance curve as a function of the current L(i), or as a function of the applied ...

Component distributor Luso is stocking a 320W low-profile panel-mount ac-dc power supply for household appliances, vending machines, control cabinets and test equipment. Part of Delta’s PMR series, the PSUs have ventilated aluminium covers and are 215 x 115 x 30mm – although the fan input means that air flow space needs to be provided above the 30mm. Four versions are ...

Schurter has introduced a through-hole fuse holder specifically designed to be compatible with reflow soldering. It is branding this as ‘THR’ for ‘through-hole reflow’. “Highly integrated electronic circuits are almost exclusively assembled with surfact-mount components and soldered in a reflow oven, however, it is sometimes necessary to include through-hole components on the circuit board,” according to the company. “THR components ...

Würth Elektronik has added devices with continuous short-circuit protection to its MagI3C-FISM family of 1W or 2W isolated un-regulated dc-dc converters. “The entire product line is certified to the current UL standard UL62368-1, but the new modules offer even more safety. They cannot be destroyed by short circuits and can withstand their isolation voltage of 1.5 kV for the SIP-4 ...

Toshiba has released a ±2.5A output IGBT gate driving photo-coupler with and isolated fault feedback, that can also drive mosfet gates. Called TLP5212, it “features a new totem pole output with two n-channel mosfets,” according to the company. “In addition, the photocoupler incorporates de-saturation detection, active Miller clamp, under-voltage lock-out, soft gate turn-off and a fault output.” Maximum propagation delay ...

Diodes has announced a 600mA automotive-compliant dc-dc converter that can run from 4.5 to 40V. Called AP64060Q, the parts include a 600mΩ high-side and a 300mΩ low-side mosfet – the latter making an external Schottky optional. Quiescent current is typically 90μA, according to the company. Two resistors are needed to set output voltage, and anywhere up from 0.8V – with ...

Renesas has unveiled a family of 700V buck regulators that can deliver as little as 3.3V and as much as 8W from the mains. Depending on topology, which can include isolated fly-back or non-isolated buck, standby power can be below 20mW in the converters, which are numbered RAA2230xx. “The converters feature a unique constant-off-time control method that helps to achieve ...

Recom has launched a range of 500W IP-67-enclosed dc-dc converters for powering loads from off-highway electric vehicle batteries. Called RMOD500-W, the supplies have an input range of 32 – 96V, which spans nominal 48V, 60V, 72V and 80V batteries. Depending on the unit, the output is 24.5, 23.5, 13.7, 13, 12.4 or 11.7V, and paralleling can be used to increase ...
