How do you Test Schottky Barrier Diodes in multimeter's?

To test Schottky barrier diodes with a multimeter, first set the multimeter to the diode testing mode. Connect the positive lead to the anode and the negative lead to the cathode; a healthy Schottky diode should show a forward voltage drop typically between 0.2V to 0.4V. Reverse the leads; a good diode should show no reading (infinity or open circuit). If you observe a low forward voltage drop in reverse bias or a short circuit, the diode is likely faulty.
