Difference between mosfet with and without logic level in inverter???

Question

I am looking for a replacement for AOD444, a n-channel mosfet in an inverter

AOD 444 , vds :60v, vgs:20v, id: 12A

I checked digikey.com, but only 2 similar one are available. They are IPD640N06L G

and

MTD3055VL

They both look similar to AOD 444, but they are logic level.

QUUESTION 1 Will it work if i substitute a mosfet (without logic level ) with another mosfet that has logic level?

Also, i found another similar one ,std12nf06l

The Continuous drain current ID at 25 degree C is the same as aod444. BUT it is smaller than AOD444 at 100 C.

QUUESTION 2 When replacing mosfet, do we have to consider the ID at TC=100 degree?

the MTD3055VL seems to be a better Rds(on), than the original which is in your favor... I would go with that one.

The others, I could link to for some reason..

lobotomy"Will the inverter work if the original one had not logic level, andMTD3055VL has logic level?

Jamie · Answer

lobotomy" the spec's you gave, the original one is a logic level.. It just does not state that.  logic level normally means the on state voltage required, which is a low level.   Since both the original and your selected are very close, your the selection is fine, also since this used in a inverter. It's a perfectfit.-- "I'd rather have a bottle in front of me than a frontal lobotomy""Daily Thought:  SOME PEOPLE ARE LIKE SLINKIES.
