Please log in for more thread options If Cgd is intended to represent gate to drain capacitance or Crss, it should run between 250pF and 400pF. This didn't change for 'A' or 'S' variants. BUZ11 was never specified for Qg - if this were calculated with a 10V gate swing and a 50V drain change, Qg is closer to 33nC (as Cgs sees a 60V change during the switching operation).

The parameters have a little bit different meaning from what you expect. Nevertheless the min-capacitances are too high. Vds, Ron and Qg are only comments in the VDMOS model. The model below is much more according to the Siemens datasheet. http://www.datasheetcatalog.net/de/datasheets_pdf/B/U/Z/1/BUZ11.shtml .model BUZ11 VDMOS(Rg=3 Rd=5m Rs=1m Vto=3.0 Kp=9 * Cgdmax=2n Cgdmin=.15n Cgs=0.8n Cjo=1n Is=2.3p Rb=6m + mfg=Fairchild Vds=50 Ron=40m Qg=27n) Best regards, Helmut | ||||||||||||||||
