The RL203 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 RL203 diode is like a one way electric valve.You can replace the RL203 with the 1N5402, 1N5402G, 1N5403, 1N5403G, 1N5404, 1N5404G, 1N5405, 1N5405G, 1N5406, 1N5406G, 1N5407, 1N5407G, 1N5408, 1N5408G, BY251, BY252, BY253, BY254, BY255, FR203, FR204, FR205, FR206, FR207, FR303, FR304, FR305, FR306, FR307, HER203, HER204, HER205, HER206, HER207, HER208, HER303, HER304, HER305, HER306, HER307, HER308, RL204, RL205, RL206, RL207, SF24, SF25, SF26, SF28, SF34, SF35, SF36, SF38, UF5402, UF5404, UF5406, UF5407, UF5408
