The SF11 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 SF11 diode is like a one way electric valve.You can replace the SF11 with the SF12, SF13, SF14, SF15, SF16, SF18, SF21, SF22, SF23, SF24, SF25, SF26, SF28
