The SF36 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.

The current can flow from only the anode to the cathode and never from the cathode to the anode – the SF36 diode is like a one way electric valve.
