What's going on with this SOA graph?
Above is a screenshot of the SOA graph from the GAN041-WSB350 datasheet.
When I saw this, I immediately got very curious, because I'm used to seeing SOA graphs where all the lines on the top right are parallel and either straight lines (for devices…

Common Source GaN HEMT breakdown
I had recently designed an array of GaN HEMTs to be used as a solid state relay. At low voltages (Vin = 24V) everything was working fine. However, when I bumped up Vin to 70V, after a couple cycles turning the SSR on and off to a 10A CC load, the…

Breakdown voltage of a back-to-back MOSFET configuration (aka "Bidirectional Power Switch")
In a back-to-back MOSFET configuration, if the single MOSFET is maximum-rated at BVDSS=100 V (like the IRF530 in the example), does that mean that the series of both has a breakdown voltage of 200 V or rather 100 V?
My argument in favor of 100 V…

HEMT device not entering breakdown region on Silvaco TCAD during IdVd analysis.What must I do to cause my device to breakdown?
I've been trying to create a HEMT device over the past couple of weeks in Silvaco TCAD. My device works just fine in low voltage operation- that is, IdVg and IdVd curves are as expected. I'm getting a clear cutoff, linear and saturation region.
The…

Clarification on relay withstand voltage
I understand withstand voltage test is to check the insulation of a product, for example between a live metal part (AC input terminal block) and a dead metal part.
I saw this specification in one of our products.
It says withstand voltage between…

High-voltage power MOSFET self-protection at low Id currents
Let's say the IXTA02N250HV MOSFET regulates high voltage in a common-gate topology. The resistive load in the source is very light and allows an output current of just tens of μA.
The MOSFET's datasheet defines the breakdown voltage BVdss @ Id = 250…

Power Rating of a HV resistor
I am conducting a project to measure Breakdown Voltage and would like to use a protection resistor, please see below.
When breakdown happens I will have something like
In this case the Power dissipated by the resistor should be P=I^2 * R, which…
