| Q. |
Switching speed of P+ junction depends on |
| A. | mobility of minority carriers in p junction |
| B. | life time of minority carriers in p junction |
| C. | mobility of majority carriers in n junction |
| D. | life time of minority carriers in n junction |
| Answer» D. life time of minority carriers in n junction | |
| Explanation: switching leads to move holes in p region to n region as minority carriers. removal of this accumulation determines switching speed. p+ regards to a diode in which the p type is doped excessively. | |
