2SK216,2SJ79 SPICE model for Multisim?

[mailfun]

Hi,,

 I have the 2SK216 & 2SJ79 SPICE model files as following :

*src=2SK216;QSK216;MOSFETs N;Gen. Purpose;200V 500mA
.MODEL QSK216 NMOS
(LEVEL=1 VTO=15 KP=80M GAMMA=18.6
+ PHI=.75 LAMBDA=521U RD=.84 RS=.84 IS=250F
PB=.8 MJ=.46
+ CBD=658P CBS=790P CGSO=26.4N CGDO=22N CGBO=852N)
* --
Assumes default L=100U W=100U --
* 200 Volt .5 Amp 6 ohm Enh-Mode N-Channel
MOSFET 07-28-1995
* 2SK216, TOSHIBA, 1993 JAPANESE FET MANUAL,
P.38

*src=2SJ79;QSJ79;MOSFETs P;Gen. Purpose;200V 500mA
.MODEL QSJ79 PMOS
(LEVEL=1 VTO=-15 KP=122N GAMMA=18.6
+ PHI=.75 LAMBDA=1.04M RD=.84 RS=.84
IS=250F PB=.8 MJ=.46
+ CBD=862P CBS=1.03N CGSO=57.6N CGDO=48N
CGBO=1.09U)
* -- Assumes default L=100U W=100U --

Enh-Mode P-Channel MOSFET 07-28-1995
* 2SJ79, TOSHIBA, 1993 JAPANESE FET
MANUAL, P.16

I copy and paste the model in Multisim, but it can't work!!!

Could you  make the 2SK216 & 2SJ79  as the "prz" file?

  I think import the prz file will be easy to finish.

Hi,

What's your Multisim version? Place the components you created on a blank Multisim file and attach it here for troubleshooting.

hi,

My multisim is V12 ,

please download and and anlyse the attach file.

Thanks!

Hi,

The main problem here is that the Multisim SPICE engine is expecting a model with four pins, however these models only have 3 pins. You need to add a .SUBCKT statement to to tie the S and B pins together. Take a look at this KnowledgeBase:

How Do I Import a MOSFET Model into Multisim?

The new model (for the 2SK216) looks like this:

.SUBCKT MOS D G S
M1 D G S S 2SK216
.MODEL 2SK216  NMOS(LEVEL=1 VTO=.1 KP=60M GAMMA=18.6
+ PHI=.75 LAMBDA=521U RD=.84 RS=.84 IS=250F
+ PB=.8 MJ=.46 CBD=658P CBS=790P CGSO=26.4N
+ CGDO=22N CGBO=852N)
.ENDS

Attached you will find the 2SK216 component I created. Multisim is understanding the model however I don't know how accurate the model is, just give it a try.

Thanks Fernando D.

But the 2SJ79 is  still not working ,would you help me?

Hi,

Basically you have to follow the same procedure, in this case the edited model is:

.SUBCKT MOS D G S
M1 D G S S QSJ79
.MODEL QSJ79 PMOS (LEVEL=1 VTO=-15 KP=122N GAMMA=18.6
+ PHI=.75 LAMBDA=1.04M RD=.84 RS=.84 IS=250F PB=.8 MJ=.46
+ CBD=862P CBS=1.03N CGSO=57.6N CGDO=48N CGBO=1.09U)
.ENDS

Attached you'll find the component I created for you.

Thanks Fernando D.!

Now I can use the model for my job.
