I have created a design with the WEBENCH for a AC/DC power supply to output 6Vdc, 0.7A. From the BOM generated, the zener (Dz) required: "VRWM of 324.006V, DCWatts 0.145W"
Is the Vrwm the working voltage of the zener? It seems unrealistic for a zener to be rated for such high Vrwm.
I attached the WEBENCH report here.
Could you give me some recommedation? Thank you.
