Question A-002-005-002

When a silicon controlled rectifier (SCR) is triggered, to what other semiconductor diode are its electrical characteristics similar (as measured between its cathode and anode)?

Correct Answer

The junction diode

Explanation

Once an SCR is triggered into conduction, its anode-to-cathode behavior resembles that of a forward-biased junction diode, with a low forward voltage drop.
