Polarity and Pinout

The BY133 diode has a cathode (-) and anode (+). In the schematic symbol, the tip of the triangle with the line on top of it is the cathode. The cathode is marked on the body of a diode by a band as shown below.
BY133 diode polarity
The current can flow from only the anode to the cathode and never from the cathode to the anode - the BY133 diode is like a one way electric valve.
