Hint: A Schottky diode is similar to a regular diode, with the exception that it has a faster electrical response time due to lower voltage dissipation. Schottky diodes are used in high-frequency applications because of their low turn-on voltage, quick recovery time, and low energy loss. Schottky diodes can rectify a current because of these characteristics, which allow for a quick transition from conducting to blocking states.
Complete answer:
Determine the diode's cathode and anode leads. The cathode will be closer to the painted line that surrounds the diode than the anode.
Connect the anode of the Schottky diode to the red positive test lead, and the cathode of the diode to the black common test lead. A “beep” or a “buzz” from the multimeter should be heard.
The multimeter will sound a tone if the Schottky diode responds as expected. The Schottky diode is not working properly if the multimeter does not produce a tone.
Now, reverse the leads of the multimeter. If the meter does not make any noise, then the diode is functioning well.
A Schottky diode has an expected voltage drop of 0.15 to 0.45 volts as compared to the standard silicon diode's 0.6 to 1.7 volts.
If the Schottky diode is part of a circuit, turn it off before testing to avoid current flowing through your multimeter, which could cause it to malfunction or be permanently damaged.
Note:
In fast-clamp diode applications, Schottky diodes are used as switches. The base junction is forward biassed in this application. The circuit speed is increased and the turn-off time is significantly reduced with Schottky diodes.
