Hi,
The attached is a HV linear regulator based on a BSP19 BJT. This is rated 350V. At 100ms in the simulation, the VCE of BSP19 suffers a transient of 400V……our contractor says that because of the 5k1 resistor in series with the collector, the effect of this overvoltage will be survivable by the BJT. We don’t agree…do you?
