What are the elements of a unijunction transistor?

🔍 Key Concepts

• Unijunction transistor (UJT) basic structure and purpose • Difference between bipolar junction transistor (BJT) and other three-terminal devices like thyristors and FETs • Common terminal names for different semiconductor devices (diodes, SCRs, FETs, UJTs)

💭 Think About

• Which option lists three terminals that all belong to the same known device type you have studied as a unijunction transistor? • Look at each choice and ask: does this sound like the naming convention for a transistor whose key feature is a single pn junction and a resistive bar? • Can you match the other terminal sets to devices you already know (for example, SCRs or FETs) and then see which set is left for the unijunction transistor?

✅ Before You Answer

• Be sure you know which device uses gate–cathode–anode terminals and eliminate that option as UJT. • Recall which device uses gate–source–drain (or very similar) terminals and compare to the options. • Confirm that the correct UJT answer must include two bases and one additional terminal.
