Pin	Signal	Direction	Function
1	A Anode	Anode	Unbanded anode. Conventional current enters here in forward conduction.
2	K Cathode	Cathode	Banded cathode. The cathode matches the bar in the diode symbol.

The diode conducts with its anode above its cathode. Schottky leakage increases with reverse voltage and junction temperature.
