Glen Chenier @ edn.com wanted to find out the characteristics of an unknown diode to be able to replace it with an equivalent one so he decided to make some measurements using his test equipment. In this article he show us how to measure the junction capacitance, Cj, and reverse recovery time Trr of a diode using a function generator and a 100Mhz oscilloscope.
