Which symbol in figure G7-1 represents a Zener diode?
- A.Symbol 4
- B.Symbol 1
- C.Symbol 11
- D.Symbol 5 (correct answer)
WhySymbol 5 in figure G7-1 represents a Zener diode. In figure G7-1, symbol 5 is drawn as a diode triangle with the distinctive bent-foot cathode bar that marks a Zener diode, distinguishing it from the plain straight-bar cathode used on the figure's ordinary diode symbols, answer D. Symbols 1, 4, and 11 represent other components in the figure, none carrying that bent Zener cathode marking.
