Nichia has announced a twin-die white mid-power LED whose colour temperature can be tuned across 2,700K to 6,500K by varying the relative current in the two die. Called NF2W757G-MT, it uses the firm’s standard ‘757’ 3030 (3 x 3mm) package – which is small compared with earlier attempts at tuneable-white LEDs. “The proprietary 2-in-1 LED technology also ...

Wolfspeed’s third-generation planar silicon carbide mosfets have been designed with an increased Cgs/Cgd ratio for better hard-switching performance and more linear Coss behaviour for soft-switching applications, according to distributor Richardson RFPD which is stocking new third-generation parts with a rugged intrinsic body diode that allows for third-quadrant operation without an additional external diode. Applications are ...

Rohm has adopted a four-pin TO-247 package for silicon carbide mosfets aimed at servers. Used for the SCT3xxx xR mosfet series, the TO-247-4L package is said to reduce switching loss by up to 35% over the conventional three pin TO-247N. The extra connection is to the mosfet source, allowing the gate driver to get at both ...

Last week it was reported that a tetraplegic man was able to walk and control both arms using a direct brain interface – a neuroprosthetic that read, transmitted and decoded brain signals in real-time to control an exoskeleton. The brain connection is through a ‘semi-invasive’ medical device called Wimagine, developed at French lab CEA – ...
