Experiment 3: Experiments for Diode Characteristics.
Objective:-
1) To understanding the characteristics of each type of diode.
2) To recognize the specification of each type of diode.
3) To learn how to test the characteristics of each type of diode by using various instruments
4) How to Judge the accepted and defective diode.
Apparatus:-
1) KL 21001 linear circuit
2) Experiment module KL 23001
3) Experiment instrument: oscilloscope and digital multimeter
4) Tool: Basic hand tools
5) Materials: as indicated in the KL 23001
Procedure:-
Part A- Experiment for silicon diode
Plotting the V-I characteristics curve of silicon diode (1) using oscilloscope.
1) Fix the module KL 23001 linear circuit lab then located the block marked 23001-
block a.
2) Insert the short circuit jumper clip referring figure 3.1 b
3) The 2.0Vpp, 1Khz sine wave to IN terminal
4) Using channel 2 for Y component to test point TP1 and TP2 then used channel 2 for
X component of oscilloscope to test points TP3 and TP2. TP1 used for vertical input
and TP3 used for horizontal input.
5) Change the display method ad oscilloscope to display the wave at screen.
6) Record the graph at oscilloscope.
Plotting the V-I characteristics curve of silicon diode (2) using digital multimeter.
1) Fix the module KL 23001 linear circuit lab then located the block marked 23001- block a.
2) Insert the short circuit jumper clip referring figure 3.2. the voltmeter and ammeter was
connected.
3) Connect the 12VDC to the .IN. terminal, then adjust VR2 (10 kΩ) to apply
4) voltage to 2 terminals of the diode as shown in Table (1) from 0.1V to 0.7V and
5) view the corresponding I f (forward current). Use VR2 to continuously adjust V f
6) to view how I f will change then record in Table (1).
7) 4 Insert the short-circuit jumper clip by referring to Figure 3.2 and short-circuit clip
8) arrangement diagram in Figure 3.3 (b) (reverse connection). Connect the
9) Voltmeter and Ammeter.
10) 5 Connect 12VDC to the .IN. terminals then adjust VR2 (10 kΩ) to apply reverse
11) voltage to 2 terminals of the diode as shown in Table (2) from 0V to 5V, and view
12) the corresponding I R. Then record in Table (2)
13) 6 Plot the values of Table (1) (2) on the coordinate paper (Fig 2)
Plotting the V-I characteristics curve of germanium diode (3) using digital multimeter.
1. First, fix the module KL-23001 in the KL-21001 Linear Circuit Lab, then locate
the block marked 23001- block a.
2. Insert the short-circuit clip jumper by referring to Figure 3.4 and the short-circuit
