Small-signal switching diodes are available in a variety of SMD packages including SOD-123, SOD-323, SOT-323, and SOT-23. The new leadless sidewall plated DFN1006-2. A package for miniaturization helps engineers meet next generation design challenges more efficiently. Futurewafer’s small signal switching diodes include a number of automotive qualified and Production Part Approval Process (PPAP) capable parts
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.

A switching diode, a type of pn junction diode, is also called a small-signal diode. Applications of pn junction diodes include rectification. Diodes for mains rectification require a high withstand voltage (200 to 1000-V) and a high rated current (0.5-A or higher). In contrast, switching diodes are designed to be used for low-voltage logic. Therefore, switching diodes provide a low withstand voltage of 80 to 200-V and a low rated current of 0.15 to 0.5-A. AS a result, it is possible to reduce the junction area of switching diodes and thereby realize low capacitance and short reverse recovery time.
Switching diodes are used in a wide range of electronic devices for various applications, including switches, transient voltage suppressors, diode logic, voltage clamping circuits, and voltage detection circuits.
