WebNov 22, 2015 · Just put several standard diodes in series, cathode-anode-cathode-anode.. etc. Each added diode gives another 0.7v drop. So to get near 5v use 7 standard diodes. You would use the created part as forward biased (as opposed to a zener - as reverse biased). Use the test setup listed here by others to test the diode string. \$\endgroup\$ – WebDec 7, 2024 · To make sure the diode is good, you should make one more measurement: using a high ohm range (2Mohm or higher) on your DMM, place the negative lead on the anode and the positive lead on the cathode. A good Si diode (the most common type of diode in today’s circuits) will usually read infinite ohms.

Diode Test: The Different Techniques Based on the Type of Diode

WebNov 16, 2024 · You can still test the diode without the Diode setting. Set the meter to the resistance (Ω) function. 2 Connect the multimeter to the diode. Connect the positive lead to the one end of the diode, and the negative end to the other. You should see a reading on the meter's display. [6] WebMay 30, 2012 · Since the zener voltage is higher than 0.7 V, the current is the same through both diodes, and P=V·I, D2 will dissipate more power, and it will be the first one to say bye. When a zener diode dies, it usually dies shorted. Once D2 dies (shorted), D1 will see the whole voltage applied, as its forward voltage. roger with ankit
