I've been designing an amplifier, with ATF33143 as my HEMT in mind. Yet, I just found out the said HEMT went obsolete. So I started looking at SKY65050-372LF as a possible replacement.
On the DigiKey website, they have "Supplier Device Package" and "Package / Case" as separate criteria for transistors. I wasn't sure what the difference is between them. So I just directly went to their respective datasheets. SKY65050-372LF has 'SC-70' as its package, whereas ATF33143 has 'SOT-343 (4 lead SC-70)' as its package.
Does this mean they have the same or different package? (question 1)
Also, I think 'current-rating' and 'voltage-rated' are the maximum current and voltage allowed, and 'voltage-test' and 'current-test' are the respective values at which the transistors are tested.
I would have thought 'power-output' would just be 'current-rating' * 'voltage-rated' but those numbers don't agree with the 'power-output' values given below.
What is the meaning of 'power-output' on datasheets and how did they get the value? (question 2)
