That's a very great find!!!

i'll check if they have the same 4.5miliohm and 180A current..

IRFB4410:

Drain to Source Voltage (Vdss) 100V
Current - Continuous Drain (Id) @ 25° C 96A
Rds On (Max) @ Id, Vgs @ 25° C 10 mOhm @ 58A, 10V
Input Capacitance (Ciss) @ Vds 5150pF @ 50V
Power - Max 250W


IRFB4110:

Drain to Source Voltage (Vdss) 100V
Current - Continuous Drain (Id) @ 25° C 180A
Rds On (Max) @ Id, Vgs @ 25° C 4.5 mOhm @ 75A, 10V
Input Capacitance (Ciss) @ Vds 9620pF @ 50V
Power - Max 370W



Eventhough for the higher breakdown voltage at the same temp, i would go for the 4110..

but that'S a nice try :wink:

Hi Wayne,

I have been using the 4410's and I haven't blown any up yet. They are in a DC-DC converter, not a motor controller, but handling similar currents and voltages. Switching speed is higher than a controller, so the lower gate cap is useful.

The point about ringing and voltage limits is a good one. There are volts and volts of ringing when these things switch; you won't always see it on a scope because it will be at high frequency and the scope probe will change it. But it does mean that the peak drain-source voltage is more than a simple circuit analysis would suggest.

I'm also going with 4410 as the 4110 genuine ones are not always available and much more expensive, the 4410 are much easier to get

 

[solarbbq2003]

also going with 18 fet controllers will make the 4410 less of a worry at higher current levels

Did anyone notice prices for IRFB4110 spiked on Digikey. I swear it was like 4 something dollars for one before. now it's like 7.30.
