... LED current. The voltage rating of the diode should be greater than the peak supply voltage transient preventing any breakdown or leakage. 150 mA ON Semiconductor Schottky diode MBR0540 (40 V, 500 mA rated) is recommended. Schottky diodes rated at 400 mA (or higher) continuous current are fine for most applications. ...
