Novel UK Si transistor switches 1.2kV and 75A through a TO247 package

Nottingham-based Search For The Next (SFN) has released data on a power transistor made using its ‘quantum junction’ transistor (QJT) technology – branded ‘Bizen’. It has a TO-247 transistor switching 1.2kV and 75A. “To get this level of performance from traditional silicon-based mosfets, the device size must be much bigger,” said SFN CEO and founder David ...

Low-jitter crystal oscillators and VCXOs are small for optical modules

Silicon Labs has introduced a family of small crystal oscillators (2.5 x 3.2mm option) and voltage-controlled crystal oscillators (VCXOs) for applications that require low jitter and frequency-flexible clock synthesis. Si54x/6x ‘Ultra’ oscillators can have jitter as low as 80fs “providing jitter margin for applications including data centre interconnect, optical transport, broadcast video, test and measurement”, ...

Risc-V RV32E variant gets Segger’s floating-point library

Segger has added support for the RV32E embedded processor core to its Risc-V floating-point library, which already supports RV32I. “This new release is much smaller than anything available to us for comparison and, at the same time, is incredibly fast,” claimed Segger founder Rolf Segger. “In the world of embedded systems, every byte counts. The Segger ...
