Previous Year Question

Correct Answer

C — Gate Turn-OFF thyristor

Concept and Reasoning

A bipolar junction transistor conducts through both majority and minority carriers, so charge storage occurs in its base and collector regions. This minority-carrier storage is why BJTs switch more slowly than majority-carrier devices such as MOSFETs.

Calculation / Key Relation

BJT: bipolar conduction involving minority-carrier storage

Exam Takeaway

Bipolar device → minority-carrier participation.

Common Mistake

Do not classify a MOSFET as a minority-carrier device; it is a majority-carrier device.
