This is my first time on these forums, i just like to ask if what maybe the cause of Schottky diode being shorted, We are using this … A very good test you can do is to check a diode with your multimeter set to the ohmmeter setting. This is a simple test we can do to check whether it is good, open, or shorted. So we take the ohmmeter and place it across the leads of the diode. The orientation is very important. Prikaži več We first take the ohmmeter and place the positive probe on the anode of the diode (the black part of the diode_and the negative probe on the cathode of the diode (the silver strip), as shown above. In this setup, the diode … Prikaži več Now take the ohmmeter and switch the probes around so that the positive probe of the multimeter is now on the cathode of the diode and the negative lead on the anode. In this setup … Prikaži več If the diode reads low resistances in both directions, this is a sign that the diode is shorted. A diode should not measure low resistance in the reverse biased direction. The diode should be … Prikaži več If the diode reads high resistance in both directions, this is a sign that the diode is open. A diode should not measure very high resistance in the forward biased direction. The diode … Prikaži več
