You can use the MBR140 model. And MBR140 = 1n5819
in a different package. Here're Intusoft's models,

..MODEL MBR140P D BV=5.33E+01 CJO=1.44E-10 EG=.69
+ IBV=6.00E-04 IS=1.65E-05 M=.67 N=1.40 RS=4.47E-02
+ TT=7.20E-11 VJ=.75 XTI=2

..MODEL DN5819 D BV=5.33E+01 CJO=1.44E-10 EG=0.69
+ IBV=6.00E-04 IS=1.65E-05 M=.671 N=1.41 RS=4.47E-02
+ TT=7.20E-11 VJ=1.45 XTI=2

..MODEL DN5817 D BV=2.66E+01 CJO=2.31E-10 EG=0.69
+ IBV=3.00E-04 IS=3.53E-05 M=.588 N=1.30 RS=4.47E-02
+ TT=7.20E-11 VJ=2.42 XTI=2

Hmm, that VJ parameter is changing rather a lot!
What's up?

Thanks,

Thanks, Win. The VJ parameter affects the capacitance versus voltage
curve.

It always warms the cockles of my heart when I see so many different
model parameters for the same device :-(

Is that cockles warming, or is it stomach acid coming up?

But it might be less than the diversity in actual parts.

Probably the latter ;-)

A word to those of you getting older...

Don't ignore "indigestion", it could be a heart attack. Mine was.

A subset? :)

My father had his fatal heart attack in the bathroom, which we were told
is common. People think they have to go to the toilet when it's
happening.

I was getting "cyclical" heartburn, every hour or so I got a pain in
the pit of my stomach. This went on for nearly a week. I was
ignoring it because the flu was going around and the #2 daughter was
having similar symptoms.

When the pain started gravitating up to my right shoulder and down my
arm I had my wife take me to the emergency room where I had the "real
deal" on the gurney.

Sure, it's quite simple. Take a 1N4148 model and make the small numbers
really small and the big numbers really big. You might have to practice a
bit before you get it right.

Jim:

"Inferior myocardial infarction"... been there...

Lateral Anterior Descending (had to get out my stent location card
from my billfold to remember that)
Here's my story...

Over 40, 50 pounds overweight, BP 150/90, resting heart rate 85, in the
bathroom one
Sunday morning, laying in a tub of hot water,

Sounds familiar
smoking a cigarette, reading

I quit smoking years before my attack.
EE Times...

Hey, I was superman, but... it happened!!!

I said it was indigestion... wife said I looked funny!

Wife called 911... paramedics saved my life...

I love that woman...

After 40... Don't mess with chest pains, acid reflux, tobacco, overweight,
high BP, flying a desk, and caffeine...

These days...

I'm back in condition, don't fly a desk, BMI spot on, triglycerides in the
sink, HDL way up, LDL way
down, resting heart rate 70, BP 115/70, running 8 minute miles every day,
surfing, fishing, riding bcycle, solving analog problems for a new
generation of digital Engineers...

Still kikin analog ass!

Neat!

That's what I need to do, get in shape. My problem is a combination
of polio and arthritis makes it difficult :-(

Ha! I know the feeling... seems like most transistor and diode "models" are
nothing more than a package for some random simulator values. :)

Yep, My wife is on my case to get the doctor to prescribe swimming.
Then I can deduct the cost of heating the pool... the solar doesn't
get it above 60°F this time of year.

Hi Jim,

It would seem to me that in the course of designing and thoroughly
testing your new line of pool heating and automation accessories,
you would certainly need to maintain a full sized test platform.

You can't do everything with Pspice.

Yeah! Try modeling the scrotum shriveling factor of 60F water
vs 80F water. Somethings you just have to test on real hardware.

I was watching a piece on a local TV statiopn last night about a young
lady who is a distance swimmer, and who has swum the English channel and
antarctica. She said that she could tell when it was too cold when her
shoulders started to turn blue!
