We need more videos on decoding the spec sheet for all devices and in this case it was focused on FETS and just what I was looking for: detailed and informative.
very well explained. but I have a question:: for IRF3205, Continuous Drain Current=110A (25 degC) and Continuous Drain Current=80A (100 degC). Package limitation current is 75A. How a ~2 square mm(cross section) pin can handle 80A ???? or 100A? not even at 0 Kelvin ....
what is the maximum current the to-220 package can handle? without burning? at constant duty. keeping it under about 50°C? I am self taught in electronics. so I likely haven't been the best teacher. is the to-220 the best package FET for high current switching for motor controllers and power supply's? does it have the best cooling and current capability? I to-220 is the package I always think of when I think MOSFET! great video. I don't understand all of it. but I'll keep watching until I do! seriously when I don't understand something I Google. and search UA-cam. since I have no one to ask. thanks for great informative videos..
Sir , all here is explained well but it assumes a constant duty cycle. Could you tell us how to determine a mosfet selection for 3 Phase Motor inverter. In such case the duty cycle is changing along the sine wave period. So which duty cycle take into account ? On the very period begining the pulses are shorter than in sive wave peak. Just for example 800W PMSM motor 220V and 4.5A current.
It should not impact the SOA, given that in general SOAs are given for pulses under saturation conditions, i.e. out of the ohmic region. In those cases, the conduction losses in the device will excede the switching losses by several orders of magnitude.

According to e package limit should be considered for upper limit and the leads could withstand this since it is very short in length.
@@selvakumarr6672 short in length, but still very very thin...

James stranger i guess Kilo or mega Ampere, for a Split of a Seconds, when contacts are molten within that Plasma.
what is a Datasheet for Dude?
Why would we choose 100uS pulse instead of 1uS or 10uS OR ANY OTHER to calculate Idm
pls pls reply
i m waiting
Do you have any video where you explain how mosfet work on diagrams?
Simple and clear explanation with examples.

use SOA limits to find how much current it can take
@@narendramane2727 SOAs are usually ploted for Tp from 100us to DC(always ON). Now let's imagine switching freq is 20kHz what gives you 50us
very good Insights, thanks for such detailed and under the Hood Perspectives
great detailed explanation, thanks a lot
does soft switching impact the SOA?
It should not impact the SOA, given that in general SOAs are given for pulses under saturation conditions, i.e. out of the ohmic region. In those cases, the conduction losses in the device will excede the switching losses by several orders of magnitude.
Nicely explaination
Great !
The worst video explanation
