Infineon Technologies & Panasonic to develop GaN devices

Infineon Technologies and Panasonic have announced an agreement under which both companies will jointly develop Gallium nitride (GaN) devices based on Panasonic’s normally-off (enhancement mode) GaN on silicon transistor structure integrated into Infineon’s SMD packages. In this context Panasonic has provided Infineon with a license of its normally-off GaN transistor structure.

MOSFETs deliver the 'industry's lowest' Rds(on)

A MOSFET family, which is claimed to feature the industry’s lowest RDS(ON) and output capacitance (Coss), has been introduced by Fairchild. The 800V SuperFET II MOSFETs enables designers to improve the efficiency, cost-effectiveness and reliability of high performance solutions requiring breakdown voltage higher than 600V/650V, and also reduces the board space of these designs by enabling the elimination of components.

Transistors & rectifiers exhibit high temperature performance

Transistors & rectifiers exhibit high temperature performance
GeneSiC has announced a line of compact, high temperature SiC Junction Transistors (SJTs) and a line of rectifiers in TO-46 metal cans. These discrete components are designed to operate at temperatures of over 225°C. The use of high voltage, low RDS(ON) SiC Transistors and Rectifiers will reduce the size and weight of electronics applications requiring higher power handling at elevated temperatures.
