A switching diode is suitable for switching a small signal of up to 100 mA, acting as a rectifier. In contrast, a rectifier diode is used for AC line rectification (from alternating current to direct current). Switching diodes are designed to handle a voltage of less than tens of volts. Those in small surface-mount packages are widely used. Topdiode offers following switching diode (part of):
