SiC mosfets hard switch 1,200V at up to 115A

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 ...

Tiny photo relay has 1mA input LED current

Toshiba has a voltage driven photo relay with a tiny S-VSON4T package and reduced input power dissipation. The TLP3407SR, features a maximum LED current of just 1 mA at the input, which represents a reduction to approximately 33% of that of its predecessor, the TLP3407SRH. This allows the product to offer a maximum input power ...
