Set analogue multimeter to x 10 k ohm. Place the red probe to the cathode and the black probe to anode and you will get a low ohm reading. Now, reverse the probe and you will get some leakage reading. That leaking reading is what tells you this is a Schottky Barrier Diode.
Schottky
Difference between Schottky Barrier Diode and P-N Junction Diode is as following...Schottky Diode1) Usually using the aluminum metal which is trivalent element. 2) Depletion layer is thinner than the p-n junction diode.3) Forward threshold voltage is smaller than p-n junction diode(0.1V).4) The junction capacitance is lower than p-n junction diode.P-N Junction Diode1) Trivalent impurity is added to the pure silicon structure. 2) Depletion layer is wider than Schottky diode.3) Forward threshold voltage is higher than Schottky diode(0.6V)4) The junction capacitance is higher than Schottky diode.

Reverse resistance should be infinite.
A schottky diode has non ideal properties. Among them is a capacitance (e. g. 900pF), which delays switching in case of a polarity reversal.
according to Texas Instruments it is a good practice to use multiple schottky diodes in parallel.

Schottky diodes are often used for RF radio frequency applications as a mixer or detector diode. Another common application for the Schottky diode is in power applications as a rectifier.

No, cos if u add water to them, they will actually blow up!
aku tengah nak belajar..nanti aku answer
pn junction diode conducts current in one directions where as the zener diode conducts in both the directions. large current flow damage the PN junction diode but zener diode conducts eventhough there is a large current........
