Dear all,

I'm always losing transistors, too. I have no idea why - maybe I'm just forgetful. ?

I think you probably mean power dissipation.

If the thermometer doesn't appear, can you still plot currents of the transistor? If you can't plot currents either, check that:

Control Panel > Save Defaults > Save Device Currents

.. is checked.

If it is, perhaps you can upload a troublesome schematic where you can't plot dissipation?

You are right. I apologize, I am writing from Hungary. My English is, um... But you get the point (:

Even if I put the cursor on the semiconductor, it doesn't turn into a thermometer.

I checked the setting, and it's okay.

The example file you can find here: /g/LTspice/files/Temp/3878_temp_test.rar

Yes, the apologies should be mine. It was clear that English probably wasn't your first language - I wouldn't attempt anything in Hungarian. But sometimes I can't resist.

Thanks for your upload, but please, next time use zip only, as per the instructions on the homepage. The reason we ask for zip is that every computer can access them? without installing and using additional utilities.

I tried your schematic, and I can plot the dissipation of both MOSFETs, Q1 and U1. Please check your settings against Save_Defaults. This is what I got: Waveforms.

Magic!
It's working!

Many thanks (K?sz?n?m!)! (:
