How to test Mosfet with Multimeter?

[Ryssen]

How?🙄
Unsoldered.

If you measure less than "infinite" resistance from Gate to Source,
then it's broken. After that, check out the article on testing Mosfets

30 Ohm..broken....
Is the Dynamik CCS in F3 supposed to work at below or above a certain frekvensy?
All the voltages are right but I get no response when turning P2 at
1khz sinus...
OT.🙂

 

[Ryssen]

Yes,I do get response,on one channel..

question about protection

hi,

i had learned that aleph-3 IRF9610 if broken, output voltage will go high and it will kill your speaker, how can i protect my speaker from this. i know there are dc protection circuit but is there any other way to protect?

thank you

 

[Ryssen]

i know there are dc protection circuit

A capacistor in serie with your speaker,but you wouldt want that if you don´t have to.... 😉 😎
