The SDM03U40-7 is a surface mount Schottky barrier diode manufactured by Diodes Incorporated. It is designed for low power rectification and signal switching applications. The device is rated for an average rectified current of 30 mA and a peak reverse voltage of 40 V. The DC reverse voltage is 30 V, and the RMS reverse voltage is 21 V.
Electrical characteristics include a typical forward voltage drop of 290 mV (maximum 370 mV) at 1 mA forward current, reverse leakage current of 0.5 µA maximum at 30 V, and typical total capacitance of 2 pF at 1 V and 1 MHz. The diode can handle a non-repetitive peak forward surge current of 200 mA for 8.3 ms. Power dissipation is 150 mW with a thermal resistance of 667 °C/W junction-to-ambient on standard FR-4 PCB.
The device is packaged in a SOD-523 (SC-79) surface mount package, making it suitable for compact designs. It features matte tin terminals, a cathode band polarity indicator, and marking code LK. The operating and storage temperature range is -40°C to +125°C. The part is RoHS3 compliant and MSL Level 1 per J-STD-020A.
