Question.1
In a small SOT-23 package transistor the top marking on the device reads “A1”. There is no other information printed on the body.
What is the correct and safest way to interpret this marking?
Select Answer
The marking “A1” uniquely identifies the exact transistor model
The marking directly tells whether the transistor is NPN or PNP
The marking is a short code that can refer to multiple different transistors
The marking guarantees the voltage and current rating of the transistor
