This normally-off 1700V JFET
offers a low on-resistance (550mO).
A completely independent, vertically integrated SiC manufacturer with the most advanced SiC epitaxial and vertical trench process technology in the world, SemiSouth utilizes a proprietary and patented self-aligned JFET
chip design enabling up to ten times smaller die size when compared to silicon super-junction MOSFETs or the latest trench IGBTs.
Specified for operation between -40 to +85 degrees Celsius, engineering samples of NEC Electronics' uPC835 JFET
op amp are available now and are priced at $1.
process is a proprietary process developed by BAE Systems.
One is left to wonder--if they used the standard, high performance topology in this op amp, why did they use the simple JFET
stage in the first op amp?

14, 2014 /PRNewswire-iReach/ -- SiC power semiconductors comprise SiC MOSFET, SiC JFET
, SiC BJT, and SiC Schottky diodes.
Additionally, the device minimizes component count and overall bill-of-material costs with a highly integrated 500V JFET
that reduces start-up losses by shutting off the current path after the device has been turned on.
The new ultra-high voltage (700V) process will include JFET
and depletion mode LDMOS for start-up and low on resistance LDMOS for power devices.
With the SemiSouth SiC JFET
and diode portfolio, we will be able to address the main power conversion and inversion circuits in those same applications by replacing silicon diodes, MOSFETS and IGBTs with higher-performance SiC technology.
The LED driver ICs have been designed to start up directly from the high-voltage (HV) supply by an internal JFET
current source and incorporate all required protection features.
The use of a JFET
as the amplifying element will prove beneficial for use in low phase noise oscillators due to its low flicker noise.
