Additional Details
The CMPD2005S has a maximum repetitive peak reverse voltage of 20V and a maximum average forward rectified current of 500mA per diode (1A total). The typical forward voltage drop is around 0.35V at 500mA. The SOT-23 package is well-suited for surface mount assembly. The common anode configuration allows for use as a full-wave rectifier with fewer components. The device's fast reverse recovery time makes it suitable for high-frequency switching applications where minimizing losses is critical.
