An SCR is made up of silicon because_____________?
Correct answer: B. silicon has small leakage current than germanium
- A. silicon has large leakage current than germanium
- B. silicon has small leakage current than germanium
- C. silicon has small leakage voltage than germanium
- D. silicon has large leakage voltage than germanium
Explanation
Silicon has much lower reverse leakage current than germanium, especially at elevated temperatures, so it gives SCRs better blocking stability and thermal performance. This makes option b the relevant material advantage.
