Question.5
A circuit is designed to switch an LED that draws 10 mA. Two transistor options are available on the Digi-Key website:
By checking the Digi-Key specifications, which device is the better choice for this application, and why?
Select Answer
TIP122-ND, because higher current rating always improves reliability
BC547B-ND, because it is sufficient for the required current
TIP122-ND, because Darlington transistors are always safer
Either transistor works exactly the same
