We offer Characteristics of Semiconductors Diodes,this experiment set-up consists of the following: Diodes: 1N4007, 1N34, 5.1V Zener and LED. 3½ digit DPM for voltage measurement Precision resistances for measurement of forward and reverse current. IC regulated power supply. The following studies can be carried out with this set-up: Forward and reverse characteristics of both Ge, Si diodes & LED’s. Study of Zener diode characteristics. The set-up is so designed that no high voltage is exposed and hence safe in handling by the students.
