- A.With the word "cathode"
- B.With a stripe (correct answer)
- C.With the letter C
- D.With the letter K
WhyThe cathode lead of a semiconductor diode is often marked on the package with a stripe. Diode packages commonly mark the cathode lead with a printed stripe or band near that end of the case, a quick visual cue for polarity, answer B. Diodes aren't typically labeled with the word "cathode" (A) or the letters C or K (C, D) printed directly on the physical package.
