HP I say nobody knows or cares cuz asc has only 1 view too

As you may recall the 'proclivities' of the (LtSpice) 'Default Diode' (among other Spice topics) were addressed last autumn ON THIS THREAD -- Please re-read the linked thread, should you yet have questions I'll happily post your Default Diode study schematics for discussion here

HP that describes problem but doesn't explain why!

HP I say you asked it exactly with like _why is ideal model more faithful to reality than model of real component?_

So big time tnx to everybody who has commented! I'll try to be patient for more help!

 

Hello,

You can switch off the flash uploader.
The filebrowser of the operating system will be used in stead.
See this thread for more info:
The usage of flash is going to be reduced in Firefox

...................
To summarize your (and, now, my) question:
The real-world circuit represented by the attached schematic and ".asc" file operate well-nigh exactly as simulated using 2n3773s and closely so with 2n3055s -- but will simulate correctly only with the 'default' NPN BJT

What do you mean "simulate correctly'?

 

@crutschow -- Many thanks for your response!

What do you mean "simulate correctly'?

Apologies for the convolution

I meant that the behaviour of the real-world circuit (equipped with 2N3773s or 2N3055s) is accurately simulated only when the .asc model 'uses' the 'Default NPN'

Specifically:
When equipped with 2N3055s, the real world circuit plateaus at ≈ +50KV (Ea) and ≈-50KV (Ek) within 50ms

When using the Default NPN model, the simulation plateaus at ≈ +47KV (Ea) and ≈-47KV (Ek) within 50ms
For all intents and purposes 'perfect fidelity' as regards ultimate EMF...

On the other hand
When using its model for the 2N3055, the simulation plateaus at ≈ +34KV (Ea) and ≈ -34KV (Ek) within 27 ms

Very best regards
HP

@Aleph(0) -- No need for the 'attitude'! -- Patience!

I believe your 'answer' is to be found in the (textual) 'declarations' for the diode -- Unfortunately I don't know how to access said info for default components

All the best
