Hi,
I was taking a look at the datasheets of the 2N4401 and 2N3904. All two TO-92 and 40V containers from Vceo though:
- the 3904 can dissipate up to 625mW and has an Ic of 200mA
- the 4401 can dissipate up to 250mW and has an Ic of 600mA
obviously they are maximum values but they are not few 250mW with an Ic of 600mA. Why would that mean that with only 250mW of dissipation it would only be possible with a maximum of 6.2mA? But then why so much difference on the dissipation equal to the container? The question arises from the need to understand which of the two is more suitable for a small class A in push pull with complementary PNPs in parallel.
The second question is related to the connection of the load which in this case is 8 Ohm but it is not important (I think) at the end of the question.
Normally the load is connected like screen 2 but can it be connected like screen 3?
Thank you!
