Default Spice Model question

Probably the wrong forum for this question, so apologies in advance. Anyone know where to find Spice models for semiconductors other than from the manufacturer? The reason I ask is that many manufacturers don't seem to provide models for all their components. For example, I am looking for a model for the ZVP3310 but for some reason Zetex's web site only has a model for the N-Channel varient (ZVN3310). Anyone know where I can find the former and other, apparently obscure models?

Ian.

Ian,

I have an old (1996-1998) Zetex library around containing the requested model for the zvp3310. I made an extraction of this model and tested it in Simterix v4.1. Courtesy of Zetex of course.


Here it is:

*ZETEX ZVP3310A Mosfet Spice Subcircuit Last revision 8/98
*
.SUBCKT ZVP3310A/ZTX 3 4 5
* D G S
M1 3 2 5 5 P3310M
RG 4 2 585
RL 3 5 1E9
D1 3 5 P3310D
*
.MODEL P3310M PMOS VTO=-2.955 RS=9.658 RD=4.9 IS=1E-15 KP=0.322
+CGSO=19E-12 CGDO=3E-12 CBD=35E-12 PB=1 LAMBDA=6.67E-3
*
.MODEL P3310D D IS=5E-12 RS=.768
.ENDS

Default rtirion,

Thanks. Any idea why Zetex would drop the model from their web site? It is not a discontinued device as far as I can tell.

Ian.

I wonder if the model was ever up on their site. The old library however is still online, but not on the Zetex site. You should be able to download it from

pspice.com

Maybe their is some other usefull stuff for you there.

Regards
