Q

What are the three terminals of an SCR?

🔍 Key Concepts

• Structure and operation of a Silicon Controlled Rectifier (SCR) • Difference between terminals of a thyristor/SCR and those of a transistor • Purpose of the control terminal in power electronics devices

💭 Think About

• Think about which option lists the typical terminals of a thyristor-type device rather than a transistor or FET. • Identify which set of names you usually see in DC power rectifier circuits that control large currents. • Ask yourself: which pair of terminals carry the main current, and which is the small control terminal that "triggers" the device?

✅ Before You Answer

• Verify which option uses the classic power diode terminology: anode and cathode. • Eliminate the option that clearly describes a bipolar junction transistor (BJT), and the one that describes a field-effect transistor (FET). • Confirm that the remaining choice has one control terminal and two main current-carrying terminals.
