Vishay has introduced a 30V p-channel power mosfet with an on-resistance of 1.7mΩ at 10V, claiming it to be the first ever. Called SiRA99DP, it comes in a thermally-enhanced SO-8 package and uses the company’s fourth-generation TrenchFET process. “Combining this low Rds(on) with a gate charge of 84nC, the SiRA99DP delivers best-in-class gate charge times on-resistance of ...

Swiss scientists have had a computational look at two-dimensional materials, like graphene, to see which will make the best transistors. From 100 candidate compounds, 13 show promise – in some cases more promise than the predicted trend of silicon finfets. The team, from ETH Zurich and EPFL (École Polytechnique Fédérale de Lausanne), modelled current versus voltage characteristics ...

SiFive has launched a self-contained and autonomous business unit to build silicon with Arm, RISC-V and other instruction set architectures (ISAs) for heterogeneous mixed-ISA designs. It is to be called OpenFive and is described as “ISA-neutral and Risc-V agnostic,” by SiFive: “Put simply, SiFive will deepen its focus on Risc-V IP, while OpenFive expands the opportunity for ...

Waygate Technologies (was GE Inspection Technologies) has launched two portable X-ray direct radiography detectors. DXR75P-HR has a 7” x 9” detector with 75μm pixel resolution. It supports ISO 17636-2 class B for weld inspection. DXR140P-HC is 14” x 17” with 140μm pixel resolution. It can be used with X-ray as well as isotopes, and is aimed at corrosion monitoring. Both detectors ...

Over-supply will drive memory prices 10% lower in Q4, says Digitimes, with weakening prices expected to continue into Q1. Memory is on course to take a 10% hit in Q3. The Q3 market is estimated to be 2.6% over-supplied and the Q4 market is estimated to be 7.8% over-supplied. Although a reduction in output is ...
