SPICE models for 2SC2705 & 2SA1145

[Gunders]

Do anyone have SPICE models for the 2SC2705 & 2SA1145 transistors?

.MODEL 2SC2705 NPN (IS=9.98627F BF=2K NF=967.67M VAF=100 IKF=49.6929M

+ VTF=10 ITF=9.9976M TR=10N

.MODEL 2SA1145 PNP (IS=10F BF=134.853 VAF=100 IKF=109.96M ISE=221.874F
+ NE=1.66575 BR=10 IKR=880.176M ISC=187.58P NC=1.90472 RE=1 RC=15.5104 CJE=2P

Hope this helps

Yes, it helps a lot.
thanks

The model for the 2sc2705 is too optimistic - BF=2k is way too high; something like 160..200 is more realistic.
