So schaut es aus wenn ein Mosfet - welches der Temperaturüberwachung und -kontrolle dient - seinen Dienst verweigert, also ausfällt.

Ich habe selbst die X-3 Serie von Qidi hier bei mir und mich aber selbst lange nicht mehr bewusst damit auseinandergesetzt.

Allerdings sollte gerade jetzt, wo die meisten Drucker mit geschlossenen Bauraum und höheren Temperaturen und Bauraumheizung daher kommen dieses Thema ernster genommen werden !!!

Electronics idea.

There are opamps with bipolar junction transistors (BJT) in the input stage.

There are others with junction field-effect transistors (JFET) in the input stage.

There are yet others with metal-oxide semiconductor field effect transistors (MOSFET) [1] in the input stage.

Idea: find an application for the bizarre possibility of an opamp with insulated-gate bipolar transistors (IGBT) in the input stage. This is more stunt-designing than anything practical.

[1] IIUC, "CMOS" opamps are really just MOSFET-input opamps. I'm not sure why the process technology name is more commonly used rather than the device type as is universally used for BJT and JFET input opamps.

i am turbo impressed with amount of quality publications, application notes etc. #ti / #texasinstruments consistently publishes. they make lots of "convenience jellybeans" (my recent discovery: #tps2114), so in theory they have no business educating nerds to - for example - "avoid common mistakes when selecting and designing with power #mosfet" etc. so, i give credit, where credit is due: thank you! #diy #electronics.

Tatsächlich ist einer der gebondeten Drähte am #MOSFET Transistor lose.
Somit scheint der Fehler der Dieselpumpe gefunden. Sobald der neue Transistor kommt, werde ich diesen in der Elektronik verbauen.

Today my new #PCBs arrived. The first is an adaptation of Stefan Wagner's #C64 Power Guard: https://oshwlab.com/wagiminator/c64-power-guard
I changed some components to what I had available. Thanks @aislerhq for manufacturing them.
Only I messed up two small details. The second #comparator is backwards, so the error #LED is practically the same as the power good LED. And I also put in the #MOSFET backwards. I'll try to mount it on its back and rotated tomorrow.

Do any of you have a SMU that can reach 1kV level? I’d like to do a simple (remote) experiment but my SMUs only reach 210V. Keithley 2410, 2470 or 2657 models would be ideal.

We are investigating switching losses of power transistors and we need to measure the output capacitance in a particular way.
