Semiconductor Device Characteristics Matching

Matching Devices from LIST-I to LIST-II

The question requires matching four semiconductor devices (BJT, MOSFET, IGBT, DIAC) with their correct descriptions or characteristics provided in two lists.

The correct matching, based on the provided answer, is:

• A. BJT matches with IV. Current controlled device
• B. MOSFET matches with III. Voltage controlled device
• C. IGBT matches with II. Power switching device with fast acting features and high power capability with voltage control features
• D. DIAC matches with I. Five layers and four junction device

Explanation of Matches

Let's analyze each match:

• BJT (A): Bipolar Junction Transistors (BJTs) are fundamentally current-controlled devices. The small base current controls a larger collector current. Thus, A matches IV.
• MOSFET (B): Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) operate based on an electric field created by the gate voltage, controlling the channel conductivity. They are voltage-controlled devices. Thus, B matches III.
• IGBT (C): Insulated Gate Bipolar Transistors (IGBTs) are hybrid devices combining MOSFET input characteristics with BJT output characteristics. They excel as power switching devices, offering high efficiency and voltage control. Description II accurately reflects these capabilities. Thus, C matches II.
• DIAC (D): The DIAC is a bidirectional voltage-triggered switch. While typically described with fewer layers, the matching leaves description I for the DIAC in this specific question context. Thus, D matches I.

Summary Table

Therefore, the correct option is A-IV, B-III, C-II, D-I.
