Polarity and Pinout
The UF4006 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 UF4006 diode is like a one way electric valve.
