spice basic, VTEMP = body

Hi All,

I download the 2N7000's mod file for simulation.

*2N7000/2N7002/NDS7002A at Temp. Electrical Model *------------------------------------------------- .SUBCKT 2N7000 20 10 30 50 *20=DRAIN 10=GATE 30=SOURCE 50=VTEMP

I think the VTEMP means body node, am I right?

Best regards, Boki.

No. It's temperature.

temperature?

Why need a temperature node ??

This allows you to create a thermal model and feed its voltage output to the 2n7000, so you can include transient thermal effects in your circuit's spice model. This is a feature that's useful for linear power circuits.

But can be done parameterized in PSpice... just use "T_ABS" or the various "T_REL...", and sweep as desired.

I love to cook with wine.      Sometimes I even put it in the food.
