An SCR is made of silicon and not germanium because silicon _________________?
Correct answer: C. Has small leakage current
- A. Is inexpensive
- B. Is mechanically strong
- C. Has small leakage current
- D. Is tetravalent
Explanation
Silicon is preferred for SCRs because its reverse leakage current is much smaller than that of germanium, improving blocking performance. Both materials are tetravalent, so tetravalency does not distinguish silicon here.
