Question 5 a) Draw the circuit symbol for an electronic diode. Identify the terminals by means of their normal names. (3 Marks) b) Describe conventional current flow for the device when, i. The diode is forward biased. ii. The diode is reverse biased. (2 Marks) c) Sketch the current against voltage (I-V) characteristics of a typical silicon semiconductor diode. Identify the important features of the characteristic by making notes on your sketch. (4 Marks) d) Draw the circuit symbol of a Zener diode and describe its I-V characteristic. By drawing a circuit and suitable waveform diagrams show how two Zener diodes may be used as a clamp to shunt potentially damaging voltages to the supply rails. (10 Marks) e) By means of diagrams identify and name the three piece-wise linear models for the diode. (6 Marks) [Total 25 marks]
