Finding Transistor Specification
Sometimes i really do not understand why the semiconductor manufacturers do not print out the full part number at the transistor front casing and left out few alphabet and give us hard time in locating the data/spec? Many times without the first few alphabet in the part number, you will not be able to locate the datasheet especially from the semiconductor databook. For example, this part number P3NK90Z which is the power FET located in the switch mode power supply actually is STP3NK90Z. You can see the part details here. If you look for P3NK90Z from the databook then you will not be able to locate the spec. However, this part number can be locate from the internet.
My concern is that what if there are other type of part number that you can’t locate from databook or internet just because of some missing alphabet in the part number? You have to be sensitive about this part number thing otherwise you will be wasting time finding a part number that does not exist in databook or internet. Why is it so difficult for the manufacturers to print the full part number? This has to be answered by the manufacturers itself. If you have the answer, we would like to hear from you.
